Haven't been viewing in a long time. Life has changed.
One morning car started but runs horrible. Being an old hand I pulled off the Idle Control Valve. It looked clean, it also triggered very fast when adding voltage to it. Cleaned it, put it back in. Car still runs crummy. Flame Trap is Clean. Pulled Throttle body, it was clean but I cleaned it anyway. Still runs crummy. I gotta keep blipping throttle to keep it running. The 'off idle' Switch on throttle body is functioning.
It has that rough running that can either be ignition OR like, water in the fuel.
Would the computer not know how to fuel the engine if the O2 sensor was not connected? My exhaust system is pretty lousy at present. I'm at a loss. Next will be a tune up but because it was a good one day, bad the next, I'm thinking ignition parts aren't the problem.
