Intermittant High Idle (again)

[Grif]

BTW started it up today, and it would hardly run at idle. Without my foot on the pedal, it would simply die. had the shop change plugs and fuel filter when it was there. But same prob. Drove approx 10 miles, parked for about 15 mins, started it again and it went up to 1500 RPM at idle. Revved the engine to see if it would shake back down, nope. Then drove the same 10 miles back home, on the way i stopped at several lights, it was back up to 2000RPM. Five mins later I was home and idle was perfect at 700. Let it sit for an hour or so, went out and started it up to play with some audio stuff, and it wouldnt idle below 2000 again.

This is frickin nuts.

Its going back to the shop on tuesday. I have nothing left to try from the advice from folx here but demand they replace the fuel pressure regulator. Either that or check every wire from every sensor. Its still not throwing any CEL codes whatsoever.

So back to the shop it went, they pulled the power steering fluid sensor off, and bam, it went back down to 1000RPM cold idle. I'll drive it a few more days and see how it goes. Luckily they didnt charge me for this re-visit.

The shop owner stated that if it were him, he would just leave the sensor off unless I was planning on racing it or somthing. I dont know if thats a good idea or not as I tend to have a lead foot.

Still, its not 700-750 which I gather is ideal. What do you all think? Leave the sensor off? (i cant imagine its very expensive, and could prolly replace it myself). And should I still demand 750RPM warm idle?
