95 Camaro Idling problem

I have a 95 3.4 V6. 4 months ago I put new plugs and wires in because the car had a dead cylinder. A week ago, the car picked up a weird miss. It doesn't happen when it is cold or wet outside, which really throws me off because an electrical problem usually gets worse in those conditions. When the car warms up and I step on the gas hard, for a quick acceleration, there is a dead cylinder, but if I left off the gas and then gets back on it, it clears itself up. Also, the problem will occur if I hang at on specific speed, usually around 50 mph.

Re: 95 Camaro Idling problem

I had a 93 a while back and I knoe they made some changes in the opti-spark I just can't remember what year I think 95. But, you can check anyways but the old optis didn't have a drain line connected. So, water would get inside and foul it up and you would get a similar effect. Another posibility is the injectors clogged or the fuel filter it self. Both or not difficult checks but if you prefer to have a mech check it the injectors can get pricey. On the newer cars when you have electrical problem its anyones guess. Best advice is get chiltons or Haynes and go threw a series of ohm and volt checks. good luck

Question Re: 95 Camaro Idling problem

I have the same problem with the 3.4 V-6. I have reason to believe it has to do with closed loop versus open loop and I don't know which is which. When the car is cold, it purrs. But soon as it reachs operating temperature it starts its popping and farting when you try to accelerate at low rpms. I hope someone with knowledge of the computer and closed versus open loop, can help us.

Re: 95 Camaro Idling problem

the problem is most likey with a dirty injector.i would recommend using a scanner to see how many missfire counters you have per cylinders.im asuming you are using good wires and plugs.when replacing these items use either the factory gm wires or car quest premumn wires.use ac plugs.dont use platnium plugs because they create more problem.try to find a shop that uses a motor vac or simular fuel injection cleaning system.the stuff you ad to the tank wont cut it.have the injectors cleaned and problem should be gone.these injectors dont go bad very often,but clog easily.
