Thanks for the tips. I re did everything checking as I went. Gaps at .028 and torque at 22lbs ft. I cleaned the surfaces on the coils and the head to make sure I got a good ground and I also tested the wires and saw 12v on all the red wires with the ignition on.

After all that I ran the car and I still got a slightly rough idle however it is very smooth once it gets going. It's also rough when I try hard acceleration. It still seems there is a problem.

Could it be the PCV which may need replacement and may be causing a vacuum leak? Also I had been told the O2 sensor might need replacing. Would that cause a rough idle?

ps. Maybe it's time for me to break down and get one of those OBD2 readers!

Thanks,

RGW
