low idle speed will lower vacuum readings... a high idle will typically cause high vac. readings. sounds like you're on the right track though.

Ok, so a new TPS makes the car run great again. However, the car will suddenly lose power drastically while at speed with not only the A/C on, but the vent, heater, or anything else that invokes the blower motor. Does this sound like a blower motor circuit related issue? Bad resistor? The switch seems fine to me because it will run the motor at all the speeds indicated and it blows fine.
If the car loses power while running the fan and I lower the fan speed setting, the car usually recovers. WEIRD
It was the ground strap that connects to the negative battery terminal. Mine was pretty chewed up and didn't have any continuity. I repaired it and voila, car runs perfect now.
