BAd idle
 

HI...
I've just had my headgasket replaced onmy 95 chevy 3.4 v6.it was running fine until last saturday i was driving and all of a sudden somethingpopped....turned out it was a stop justin front of the o2 sensor onmy exhaust manifold...since then as soon as i start the car it runs ok -ish its idle is bad u can feel it shake and also when accelerating you can slighty feel it...whatcould it be...cananyone help me!!!!
THX guys

is there any oil? i used to have a bad vibration especially at idle a few months ago.

what caused the o2 sensor to blow, may have a plugged cat creating a ton of back pressure

good point. that happened on my dads vette. it caused a manifold gasket to blow too...

ya my gasket had to be replaced when i had that problem.:(
