Random hesitation and backfire
Random hesitation and backfire My car just today started hesitating for a second and then it would go again. at first it was only around 2k rpms and in a certain gear. Now it is becoming more random but doesnt seem to do it in the higher rpms. I was at 2.5k then it just dropped foot on the gas to 2k then again to about 1.7k and then back up. I am not sure what could be causing this problem. Also I have had random backfires ever since i had a crankshaft sensor problem. That sensor has been replaced within the last week but i still get a few random backfires
it got worse today mostly when i got to 4th gear at 2k and 5th at 1.5k. Almost undrivable. It was almost like it was trying to shut off and the rpms would even go to 0 completely while i am driving and cant really give it gas at all. If i do it just backfires really loud a few times
Not on my T/A, but my Maxima once had some sporadic hesitation at different RPM's with no CEL. It was a coil pack going out. Not knowing which one, I swapped them all with my spare set. One day I may have to figure out which one is bad.
Does the LS1 have 8 or 4 coil packs? If there is one per cylinder I wouldn't think it would cause that much trouble, but if they're doubled up that might make more sense.

Sorry. I do no own a T/A at present and could not remember the setup. My '98 Grand Prix GTP had paired coils which were interchangeable between that 3.8 and the 3.1 in my mother's Grand Am back in the day. Currently my V6 Maxima and LS2 GTO each have one coil pack per cylinder as well.

It ended up being the wiring to the crank sensor. The headers had melted through the heat shield and plastic housing all those wires. But now that I had someone fix that I have another problem of my check engine light flashing only when i accelerate so i cant get a code and I almost feel a little bit of a clunkiness in the gas pedal. I was told to change my o2 but not so sure thats all thats wrong
