Thanks for the waterin the fuel problem tip. It makes sense to me. I do notice that every vehicle I drive seems to have fuel related performance problems. I live in coastal Mississippi and it has been very hot and humid here lately. I will try adding alcohol to all my vehicles when I fill up next time and see how they do.
Well she finally did it to me tonight. It is surely ignition related. No spark condition when being cranked and took about 10 minutes before it would crank this time. Fuel pump ran OK, had gas at fitting, no spark. It finally cranked after waiting, but this time it idled low and almost wanted to stall. Shut it down and restarted again, this time it idles OK. Drove off and drove it 10 miles down the highway at 65mph. It made the hard jerk, almost as if the ignition had shut down and restarted very quickly. I doubt it'* the ignition switch because if I turn the ignition switch Off and On quicky, it takes about a second before it starts back up. This was a very sudden Jerk of the ignition system.
After driving those 10 miles at 65mph, it stalled while coasting to the redlight at the end of the road. Started right back up, idling Ok. Drove back home 5 miles stop and go with not one problem until......
Backed car to the back of the driveway (it'* new permanet residence now cause I don't trust her). Just for giggles, I turned the wheel to the right and it dropped RPM to 300-400 and then it shot up to 1500 and stayed there for about 2 seconds before idling back down. Turned the wheel again testing the pressure switch a few times and it idled as expected. Aggravating,@#%@!! car!!!
Could a PCM be causing this? How about the ESC up on the firewall? Those are still original.
Once again, much thanks for all the help given so far. I have gotten a lot of stuff sorted through and fixed by all the help ya'll have given me.
