    What is egr tube my car runs loud price broken they say that’s name but don’t make no more

  2. Avataaar/Circle Created with python_avatars Jonny Abs says:

    Oil cap ass end down on the dirty airbox? Awful. Picking up all that dirt.

  3. Avataaar/Circle Created with python_avatars Calm Winds says:

    Eric, hopefully you’ll be able to help with the following. I have to take out the secondary air injection to get to the exhaust manifold however I’m having trouble disconnecting the wires. It seems like you disconnected them before the video started. When I changed my spark plugs I had no trouble disconnecting the wires that were right above them but the wires connected to the secondary air intake are giving me trouble. Any tips? Car is Chevy Malibu 2012.

    Thanks for showing us

  5. Avataaar/Circle Created with python_avatars David Ridley says:

    Could a too high reading be caused by same part?

  6. Avataaar/Circle Created with python_avatars Jim's Innovations says:

  7. Avataaar/Circle Created with python_avatars shenanigans alv says:

  8. Avataaar/Circle Created with python_avatars David Partyka says:

    What was the torque spec for those bolts, was hopping your were going to say it! 😛 Having a hell of a time finding it, its not in the Haynes book.

  9. Avataaar/Circle Created with python_avatars Thomas Devine says:

    With the pressure sensor measuring the low side pressure you could add a inline sensor before the valve and a pot to adjust the value for about fifty bucks.

  10. Avataaar/Circle Created with python_avatars Phillip G says:

    Love the Video but you made it look like that GM had two different sets of nut size on that part. Also you didn't explain that there only three bolts and nuts. You made it appear as if their six of them.

  11. Avataaar/Circle Created with python_avatars bgregg55 says:

    That's the only system that has ever failed me on my 10 year old LE5 ecotec. Lucky for me, I live where emissions testing isn't required so I quit fixing it after the first failure.

  12. Avataaar/Circle Created with python_avatars jdaling12 says:

    “There…all torqued down to factory specs” That was awesome!
    That is the real deal

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

    Thanks for the video.

  14. Avataaar/Circle Created with python_avatars Jeff Miller says:

  15. Avataaar/Circle Created with python_avatars bradley goode says:

  17. Avataaar/Circle Created with python_avatars kylie Conway says:

  21. Avataaar/Circle Created with python_avatars 69chargerforever says:

    Times like this you need to have a generic closing set up so you can just grab it and edit it in.

  37. Avataaar/Circle Created with python_avatars now534 says:
