engine miss I don't own an LS1 yet, but someday I hope to. I do have a 95 firebird with a 3.4 that has a cold engine misfire. I've replaced the plugs, wires, and coils. It only misses for a couple of blocks and then it smoothes out. Tonight I notices a strong fuel odor inside the car after I started it and let it idle for a few. I don't know if it matters or not but the car doesn't warm up very well when it's cold out. I know it's not LS1 related, but I see there's a lot of experienced people here and hope that maybe someone can help. Thanks
get it scanned id have it scanned i think autozone does it for free.sounds like a bad o2 sensor.because it clears up after its warm.or a coolant temperature sensor.they are so many things it can be.id have it scanned.
