Tps voltage and idling issue
Tps voltage and idling issue I have a Ls1 with 96mm typhoon intake and a 102mm tb and a 104 lid and 1 7/8 headers with 3 inch exhaust. M6. When I start up it idles at 1300 then drops to 500 then goes to 850. When car warms up it idles at 900-1000. If I have the a/c on and I'm going 40mph and put it in neutral it will stay at 2k till I come to a complete stop. But this weird idling is not everytime. So I'm thinking I have a vacuum leak I can't find or its a tuning issue but I don't know. Do you have any idea?
Plus for the voltage I adjust the car off to .50 and then at wot it shows around 3 bolts, Is that normal? Also what is the voltage suppose to be when the car is running?
