I filled up my tank at the local Chevron station and ran the truck at 60 on the freeway for about 30 minutes and when I stopped at the off ramp the truck was not idling smooth at all. I re timed it and put new plugs and points in and no luck. It runs OK? After it accelerates but flattens out.
I checked the exhaust and it was white even after the carb was set by the book. Could it be the E85 or and additive they put in the gas.
I didn't replace the condenser yet.
