Sorry for the length of time on my last response, I was out of town. I REALLY appreciate all the help you are willing to provide me! :D
My check engine light was on for a month or two and I took it into them to fix whatever was causing that and they came up with those two sensors as being the issue. After they supposedly replaced these 2 sensors the light went off but the issue with the RPMs jumping began as soon as I ran the heat/defrost/AC.
They CLAIM they did a pressure check and they found no problems. They were also trying to force me to do a coolant flush, at 90.00, although one was done approximately 8 months ago. They did not run a diagnostic on it, they immediately went after the thermostat and stated it was bad. When I got the old one back you could push it open with your fingers and it would close again. : : They also wanted me to spend 100.00 for them to do an A/C inspection. I'm thinking they just want me to keep spending money.
The car ran fine before they did this work (only issue I had was the a/c started blowing warm last summer I assumed this was a freon/condensor issue and I was going to take care of it this summer, but these other issues occurred). I had no issues with RPMs jumping nothing, nada, zip until these sensors were replaced. I explained this to the guys at the shop and all they said in a real nasty tone was "I can't speak to how your car was running before." :Shock: All my vehicle maintenance and repairs are in their records!
The statement about my heat and defrost running off the a/c compressor still makes no sense to me.
This is funny, when I took the car in I put in writing the problems I was having, I espcially made reference to the fact that I was NOT running the A/C when it would overheat, that the A/c stayed warm so there was no point in running it. When I picked the car up and looked over the paperwork they had it typed in there that the car was overheating while using the A/C! Idiots!
