Buick 3800 barely runs on cold start...then runs fine
My wife'* car 99 Buick LeSabre just developed this issue. She thought she ran it out of gas (it was very low but I'm not sure it was out)
The car starts, misses and sputters like its running on 1 cylinder, but will after a bit, warm up and smooth out and run down the road just fine. When its misfiring I can smell raw fuel in the air and there is a loud woosh of air coming from the airbox (or under it).
It I turn it off and warm restart, it will miss (and not take throttle) for a minute or so but returns to normal again.
Not sure what the most likely culprit is: EGR, coils, fuel filter....?
