    This is on a 91 Prelude 2.0Si, but the same thing could happen to a civic........ok sometimes the motor will hesitate under load, almost feels like a miss, and intermittantly (sp) I will have a rough idle...I cleaned out my distributor, valve timing is good, fuel pressure is within specs, so is compression...not sure on the condition of the ignition module...I'm a mechanic and this is confusing me, so any advice would be helpful...thanks 8)

    What do the plugs look like? If they are fine then I would test the ignitor.

    Do they look fouled though? When I had a major fuel problem when I first ran my swap I fouled the hell out of my plugs without even driving the car more than 5 miles.
