  • 94 camaro 3.4 V6 A/T Problem when warm

    Hello to everyone..

    My car is having a problem. When cold runs perfect, once it get warm its a little bit rough, like when you have a problem with one spark. but I have changed all sparks its plugs.. It began since a plug get disconnected from a spark. When the car get cold again runs perfect.. And the when warm its wrong again.. What Could i check? Injectors and ignition module are almost new.
    Im gonna change the three coils for accel coils..

    Help me please.. Have a great day..

    Thanks

    I would stay with stock coils they are better than accel coils.

      That would be where I would go next, is with the coil packs. And I agree with ssms5411, stay with the stock style. The engine was designed to run with those. I saw a brand new coil pack on a buick regal at work the other day that was arcing through the case and grounding on the mounting screw. The car was idling like crap.

        Hmmm, if it's the coil or spark problem then there would be a skipping thing going on during idling. The exhaust note itself won't sound even. I think this has something to do with open loop and close loop. I have a 2.8 bird with MAF which is constantly stuck on open loop.

        I think yours doesn't have a MAF but MAP.

        Are you throwing any codes?
