I have pretty much done a complete tuneup on my car ( new plugs, wires, distributor cap, rotor (soon), PCV valve. Cleaned EGR valve, fuel treatment, lots of carb cleaner, fuel filter (soon, its being difficult).

Runs better than ever, Great mileage, at speed.

Still can idle rough to VERY rough :^(. Rarely, VERY smooth :^), but sometimes.

I've read some archives here and have had a few ideas leading to the electrical system then tonight I discovered something new.

The car runs pretty good during the day most of the time. At night after work it can be tough to get it to idle smooth when I first start it. Tonight when I got near home I stopped for a burger. Sitting in the drive through line I noticed when I let my foot off the brake the car would run pretty smooth :^), foot back on brake was a rough idle. Then the light bulb came on over my head, Doh.I had the headlights on ( bright only work) and the radio. Brake lights or whatever seemed to put it over the edge to a Very rough idle.

Where do I start with the electrical system ? Battery, alternator, coil ???

Or what ? I'm starting to think its not a burnt valve or piston and this car might last a while longer. Haven't wanted to pay for compression test or computer analisys, Last resort.

Thanks, John
