1997 camaro 383 issues
I have a 1997 camaro with a 383 stroker. The car is cammed. Not sure what all else is done. The car sounds like it's misfiring when I first take off or if I am driving under 2,000 rpms. Also if I try to keep a consistent rpm it starts to jerk. But if I punch it the car runs normal. I just replaced O2 sensors, they seemed to help a little but didn't fix the problem. Btw the car has no cats just mufflers.

GM Performance or something else? I replaced the Opti on my '93 twice in 6 months. I didn't go with the GMP the second time because I was selling the car,had I kept I would have.

It was with all GM parts. I only have like 1,000 miles on car since replaced. When the optispark went out on me the car was really hard to start and ran crappy. I know that's not the only symptom of optispark tho

I actually had an exhaust leak and got that fixed. Thinking it was the problem, but it wasn't. I have not checked fuel pressure. My air to fuel ratio gauge looks good tho. All the work was done to the car before I bought it. I've had it for about three years.

My LT1 ran like that for a while and it turned out to be a burnt plug wire on number 8,it would come and go as it shorted out or not. Seemed to not do it when I ran it hard and when I wasn't it would act all nutty .I guess there was enough vibration when I hammered on it to keep the shorting out to a minimum. Eventually it got worse and we found the issue.

also test your engine temp sensor, its at the front of the waterpump. http://shbox.com/1/4th_gen_tech2.html#ect had one go on a truck and it would only run half way right at wot. tested it and it showed -40 degrees. it was getting way too much fuel.
