    Hello, thanks for your video. I also did all those tests and more and I can't find a solution, but now I'm going to try the one that you. made. I still ask you, otherwise it's the intake gasket, I have a 2008 Toyota Corolla with 230,000 km of manual gearbox, 1.8 liter engine, type 1ZZ-FE. The fault is that when you turn it on it starts with 1300 rpm and as it warms up it goes up to 2000, that is, it does the opposite since I understand it should go down to about 900 rpm. and when I'm hot I go out and when I make the gear changes I see that the rpm oscillates between 2000 and 1000 rpm and when I continue the march the minimum is 2000 rpm. If I leave it running stopped the car stays at 2000 rpm. I clarify that with a scanner it does not give an error. Well, we took out the carburetor, total cleaning including the MAF sensor of the filter, I clarify that you cannot take out the IAC valve to clean but the carburetor body was immersed in non-abrasive remover liquids and a lot of dirt came out. We measured TPS and IAC with a multimeter, simulated with power and everything was fine. We checked the pipes that had never been touched and were spotless. We put everything together and it starts doing the same fault. Then I disconnected the EGR vacuum valve and there the rpm's dropped a little but after five seconds it accelerates and when connected it returns to 2000 rpm. The same if I disconnect the PCV valve and it idles at 200 rpm until it shuts off. Could it be a fault in the EGR vacuum valve or Crankshaft Sensor and cams (CKP and CMP)?

    I have to ask – why didn't you just disconnect the throttle body and move it away to the side, rather than unhook all of the hoses from it? That way you wouldn't have to worry about the coolant hoses. (pinching them, possibly cracking, etc). I'm chasing a P0171 right now.

    I did this and now my corolla is idling crazy. Also my brakes are very stiff. What happened.

    HEY THERE VIEWERS AND WELCOME BACK TO THE SOUTH MAIN AUTO CHANNEL,

    TODAY WE HAVE A MATRIX AT THE SHOP, IT'S GOT THE BIG 1.8, AND THE MONEY LIGHT IS ON, SO LET'S GET TO IT !

    There, fixed it.

    7 years later you did the exhaust too haha

  8. Avataaar/Circle Created with python_avatars The Left Nut says:

    There is one vacuum hose he missed behind the throttle body!

  9. Avataaar/Circle Created with python_avatars Joshua Lindabury says:

    Help! I unhooked the hoses from the throttle body but it looks like coolant coming out!? Is this normal?

    My toyota hilux vvti is loosing power more especially when driving uphill or even pulling a small trailer. The manifold was removed before when I fitted the water bypass pipe so, the mechanic thought it might be a bad gasket. I bought one and fitted it but, the car doesn't pickup the way it should still. It has a very slow response.

  11. Avataaar/Circle Created with python_avatars Mogase Segopotje says:

    No silicon seal needed?

  12. Avataaar/Circle Created with python_avatars Jerrin Mathew says:

    just a quick question about the intake ports on the engine block. the three sort rectangular ports between the intake ports, what are they meant for as i would like to know what their purpose is .. cheers 🙂

  13. Avataaar/Circle Created with python_avatars Michael Morris says:

    Thank you! Very to the point and informative.

  14. Avataaar/Circle Created with python_avatars franklinslagpile says:

    Any need to bleed air from the cooling system after doing this? Seems like clamping off and removing the coolant lines to the throttle body as you suggest would allow air into the system.

  15. Avataaar/Circle Created with python_avatars Kendall Casperson says:

    So I’m replacing my dipstick tube and I need to take the intake off to get in there. Do I have to replace my gasket when I take it off???

  16. Avataaar/Circle Created with python_avatars Jeff Spicoli says:

    this aint for the newbie

  17. Avataaar/Circle Created with python_avatars nuts 4 knives says:

    How do you diagnose it? My vibe randomly idles rough. Especially in gear at a light or stop sign. I sprayed it downd with carb cleaner but it didn't change the idle. I already replaced the maf sensor. The car is an 06 but it only has 40,000 miles

  18. Avataaar/Circle Created with python_avatars Michael Dooley says:

    Thanks man you just saved me like two hundred bucks

  19. Avataaar/Circle Created with python_avatars Martin Albert says:

    Should you replace the throttle body gasket too since it is likely to go bad too?

  20. Avataaar/Circle Created with python_avatars jason stride says:

    where is the 2009 Pontiac vibe 1.8 l code reading port?

  21. Avataaar/Circle Created with python_avatars Joshua Sales says:

    I have an 04 Corolla. Was just wondering if this could throw some air sensor codes at me on an obd2 scanner. I know for a fact I need to replace the intake gasket.

  22. Avataaar/Circle Created with python_avatars Central Coast Corolla Project says:

    Nice quick presentation of things to be disconnected. I will have to replace intake manifold gasket on my 03 Corolla soon.
    I look forward to any future 03-08 Corolla/Matrix or Pontiac Vibe videos. 👍
    😎

    a local 'mobile mechanic' will replace my gasket with a Fel-Pro one after 275K miles in my 2000 Corolla I have driven 20 years … it is due for some problems and the rough running and poor acceleration seem to match the problems noted … a 1-time job for an experienced guy and pay his fee.

  24. Avataaar/Circle Created with python_avatars Hola! Russell Wiley says:

    There's another hose behind the throttle body. Mine disconnected and was causing misfires. Sneaky little sucker.

  25. Avataaar/Circle Created with python_avatars Wesley Nunez says:

    Thank you for demonstrating this process. It was extremely helpful.

  26. Avataaar/Circle Created with python_avatars George G says:

    Once again thank-you for the great video, is got nice and warm here in Toronto and I did replace the gasket, I took my time and it only took me 30 minutes. All I can say hats-off to Toyota a real jewel of a car to work on, even though my 2004 Matrix is 16 years old with 296,000 kms All the bolts came off perfectly unlike the american cars.

  27. Avataaar/Circle Created with python_avatars DA REALIS says:

    This guy is a great mechanic! He gets straight to the point and I can tell he's very genuine and would never rip off anyone or over charge. We need more mechanics like him

  28. Avataaar/Circle Created with python_avatars Andrew Droegemeier says:

    If your power brakes stop working after using this technique than another little hose broke loose behind the manifold. Took us a day to figure this out 🤦‍♂️

  29. Avataaar/Circle Created with python_avatars George G says:

    Just a thought if you still have the original thermostat this may be a good time to replace full access with the manifold out

  30. Avataaar/Circle Created with python_avatars George G says:

    Great video I test mine the same way and guess what intake leak at cylinder 1, as a temporarily fix I cleaned the area of the leak started the engine and then I Brushed on engine oil over the leaky area and the vacuum sucked in the oil and sealed the leak. It's been a week now and no codes. If I get another code I may brush on gear oil this may last longer and I will replace the gasket when the weather gets warmer. Very cold her in Toronto Feb/18 2020. The gaskets are cheap always go with Toyota or Fel-Pro bet they will be very close to same price

    ok found how to fix

  32. Avataaar/Circle Created with python_avatars Chris Cook says:

    Disconnect battery first?

  33. Avataaar/Circle Created with python_avatars harry says:

    The process was a little different on my 03 corolla s, 5 speed

  34. Avataaar/Circle Created with python_avatars thewildwhisper says:

    Did you have to drain the coolant first?

  35. Avataaar/Circle Created with python_avatars John Grande says:

    Just did this on my 2004 Corolla and now it's running like crap, throwing misfire codes and the brake pedal will not depress…..WTH happened??? Ideas, fellas???

  36. Avataaar/Circle Created with python_avatars SurfnSCal says:

    I replaced my intake manifold gasket by unbolting the intake manifold and using a pick I was able to get the old gasket out and I was able to work the new gasket in the grooves of the intake manifold. Bolted it all back together and didn't have to disconnect any hoses or cables to throttlebody. I did remove the radiator fan shroud assembly for more room for my hands. Did the job within an hour and my fuel trims immediately reduced but I think I still have another issue causing my lean condition as the code returned once months later.

  37. Avataaar/Circle Created with python_avatars Josh Rod says:

    Wow how easy, thanks man

  38. Avataaar/Circle Created with python_avatars Drew says:

    I did this and now I'm getting a p0505

  39. Avataaar/Circle Created with python_avatars THEPLANETEARTH says:

    Always replace the throttle body gasket with the intake manifold gasket

  40. Avataaar/Circle Created with python_avatars Steve Chavez says:

    I replaced the gasket now idles very low

  41. Avataaar/Circle Created with python_avatars Duncan Mac says:

    Thanks for the video.

  42. Avataaar/Circle Created with python_avatars Robert Sharp says:

    THANK YOU Super Amazing. I need to change out the Knock sensor. Has anyone been able to change the knock sensor from the bottom without removing the intake???

  43. Avataaar/Circle Created with python_avatars Sarah Wills says:

    The bolts holding the manifold on wouldn’t budge! I got the one in the middle but the outer ones wouldn’t move and I didn’t want to strip them. Any recommendations?

  44. Avataaar/Circle Created with python_avatars monkeydude3987 says:

    Hey thanks for uploading this, I am planning to help a friend replace this gasket on his Vibe. Nice to see how it comes apart before I open it up. Great video!

  45. Avataaar/Circle Created with python_avatars Mark E. says:

    Do you have to disconnect the battery terminal when removing the intake manifold? Great video sir :)!

  46. Avataaar/Circle Created with python_avatars stewiegonebad says:

    Thank you for posting I just fixed this issue in under an hour saved a ton not going to the mechanic!
