Thanks Dale. The CPS is next on my list. But here is what has been done so far.
Took the car to my "Trusted Mechanic" this morning and explained the issue(s). He took it for a test drive and did NOT have any problems. He did clean up the battery connections & recommended that the cables be replaced (corrosion INSIDE the cable near the connectors - will do sometime next week), and cleaned the throttle body. He also tested the fuel pressure and spark and said they were working fine. I don't remember him mentioning the CPS, but he may have tested that.
Idle is now back up to somewhere around 800 RPM after warmup. I have had it do this in the past, after the battery is disconnected and then reconnected (resets computer?).
BUT ... When I jumped back in to drive it home, it died again right there in the parking lot. Started right back up & ran all the way home.
I was going to replace BOTH the Auto Shutdown & Fuel Pump relays (they work "together"), but the parts store only had one in stock. So ...
I
replaced the Auto Shutdown Relay with the new one and
swapped the Fuel Pump Relay with the Starter Relay (they are all the same). I figure the following:
- If the Auto Shutdown Relay was the problem - it is FIXED.
- If the Fuel Pump Relay is intermittent, the car won't start some time in the future. This is still not good but much better then having the car "quit" while driving.
- If none of these relays are going bad, the problem will return as before.
Then it would probably be time to go for the CPS.
Anyway, I made the replacement & swap and then took it for a 15-20 minute test drive. It worked just fine with no sign of problems. I will let everyone know if other symptoms show up.
Take Care,
