ok and someone else said this too, Does this happen consistently? with no CEL?

 

I told you.

And yes it will misfire without CELs.

My car has done it, with someone else on this site in the car.

Get OEM ACDelco iridiums.

Don't run anything other than those.

Trust me.

 

let the dealership fix it.

and cuda, you live in bel air. i think i might have seen you at target last week....

 

yep buyin a father's day card

 

Ok, brought the car in yesterday and showed the techs there the vacuum tube not in place with the plastic stem snapped off. They are gonna put in a new MAP sensor. If the insurance company doesnt warrant it as happening from the accident they said the warranty will cover it. He was absolutely 100% certain this was causing my car to accelerate funny along with other friends i talked too. This vacuum line is in charge of maintaining the fuel/air mixture, and if it runs to lean/rich, it WILL misfire. That would explain why it might be misfiring if that is the cause of the boost drops and abnormal acceleration when WOT. under normal acceleration there is no boost drops and the no hesitations. Will update once taken care of.
