Hello all, I'm a neebie.
I have a 95 LT1 in my 71 olds vista cruiser with a 200r4 trani.
I noticed today for the first time on medium to hard accl. the car stumbles or misses then backfires. Once that happens it clears a little, but is still noticable. On easy acceleraton I really cant feel or here it.
I do have a 58mm t-body and a larger mass air with a cone filter.
thanks again, mike
Thank you for the help. The opti spark, O2 sensors, and plug were new when the engine was put in. The opti spark is the later part#. I scanned for codes and none showed up.
I have had the car running for 2 years but now its a dailey driver. I live in LA
and traffic sucks. So I believe the miss is new. I have not driven for 1.5-2 hours straight since completion.
Thanks again for the help, mike
