[QUOTE="KKanoza58, post: 439316, member: 21198"] Howdy, Well I'll knock on wood...but I think I got the stalling issue licked. I did replace one "CPS", the Crankshaft position sensor. It fired up and I ran the engine at the house for about an hour to make sure I could trust in traffic. I took a short trip to gas up and went back home. No issues. Next day I took it out on our local highway and it did fine!! (All the cleaning and replacing I've been doing has the old girl running like a roadster). So, I almost got it home...died on me!! WTF? I tried popping the clutch while I was coasting, but that didn't work, So I stopped and waited for no more than a minute and it started up immediately. I got home that night. Next day after work I went back out to work on it and it just cranked, no start. I went around to all the connections, wires, harnesses, ect. and jiggled everything. Tried starting again...BAAM, started right up and continued running! I knew something had to be shorting out so, while it was running I went back and jiggled everything again and lo and behold when I barely touched the Camshaft position wire, it died! Glory...I took off the dist. cap and that 3 wire harness was practically worn in half! I'm waiting for the new other "CPS" I ordered to come in but in the meantime, I separated the 3 wires with elect. tape, put everything back and I've driven to work the last 2 days with no issues...
