Pete, check the resistance at the DME coolant temp sender. I think I had a problem with mine years ago. Mine would run fine for about 30 minutes, the stall. It would crank but not restart. After 30-45 minutes it would crank and start fine.

OK..I drove the car to work yesterday. Idled OK..but it is weird. Sometimes it runs like a scalded cat, then later, in the same drive, it can't get out of its way from a standing start, or even accelerating at highway speeds. The idle becomes noticeably rougher with A/C on. Last night's new trick was the car missed, or sputtered on a couple of acclerations. I am thinking perhaps ICV, but the hesitation on acceleration has me wondering.

I am starting to think it is the TPS...

Poor idle - particularly a high idle condition - Check.
• Engine cuts out to an idle condition during acceleration - Check
• Poor power at various RPMs (various throttle positions) - Check
• Surging idle - Not sure.
• Misfire - Check
• Stumble during acceleration - Check
