Driving it off the cliff

[Stl-986]

Video from this morning. Car warmed up. Not sure how the audio will be from the gopro. I'm not even sitting in the car when I did this.

It is back to do exactly the same thing as before. Constant misfire on cyl 1-3 but I haven't touched a single thing since last evening when it was doing so much better & idling higher.

Cat test up next as soon as it cools enough some for me to get under it.

Interesting.
May be time to disconnect and block off the SAI which I think is just one vacuum hose connected to the intake plenum. easy to get to.
Also disconnect the EVAP system more of a PITA.
Just to see if doing that changes anything???

couple of question????
Have you recalibrated your E-gas pedal lately????
Also have you checked for exhaust leaks???

Exhaust leaks is where a smoke machine could be handy.
plug the tail pipes and the intake.
Insert the smoke into the tailpipe
