fluctuating tps voltage + %, coolant temp and iac the car is a 94 formula with automatic, full bolt ons and a 218/230 nitrous cam.
i have scanmaster on my column and i constantly look at my readings.
tps voltage is very erratic as well as coolant temp
(new iac and tps but tps still reads erratic)
it is idling high and my iac counts are going to 160 every time i restart the engine
(last night it was running good my iac counts were 18-22 and a dead stop and tps voltage was at .67 coolant temp was reading 186- elec water pump)
every once in a blue moon the readings will be steady and everything is running perfectly
car is not throwing any codes so i am at a loss.
this is all with the car cold or warm it doesnt matter with key in on position and car off
