okay I have tried two different coil packs and two different ignition modules in all the different configurations possible and I can't solve the problem. So I am wondering if both the coil packs and modules are tost or if I am chasing after the wrong thing. symptoms are that under idle or light throttle I have a very bad miss. but if I floor it it runs fine. I can run up to 20 psi (alky) without the miss which puzzels me. it tends to be okay when the car is cold but gets real bad after it warms up. any ideas, I guess I could replace the coil pack and module again but I would rather not if I am chasing my tail.... thanks!
