po300..please help me
So here is my deal....i am throwing this code and like everyone else (yes i did a search) the car stumbles and shakes from 2K to 3K. so far i have
replaced a entire mass air flow sensor
replaced fuel filter
checked for vacum leaks
check plugs and wires
checked fuel pressure.
everything checks out fine. if i erase the code the car runs fine for about 1 day and then everything starts over again. Can you guys please help me find out where to look and what to check next> Thank you so much
The car is a 98 ls1 camaro all stock but headers and exaust
45K miles on it
6 speed

I solved the problem by changing #8 plug which still looked like original one and had almost no core left. It would still fire so it was not a more specific p0308 code. yes it's the back pass side one that you crall onto the top of the engine to replace after you swing aside the coil rail. I was even getting the rotten egg smell from the cats due to the misfire. and this fixed it before I ruined the cat.

alright i got a new set of plugs goin in this weekend. I am praying that this solves it. its so weired how the problem comes and goes..it seems to me if a plug or wire was shoot it would happen all the time. guess its time to get the knuckles bloody and change all these plugs out.
