tps
 

i have a 5.0L cobra and i recently put a new intake cam and throttle body on it and it runs great at idle but when im driving down the road and i hit the clutch in the throttle seems to stick around 1200 to 1400 rpm...i checked the tps on the throttle body..seems to be right ...any help? thanx

this process works great for me everytime, hopefully it works for you too

worked for me too

The best way to try to fix this problem is to check the TPS voltage with the car off key on. With the butterfly closed the voltage should be at .99 volts. At wide open throttle the voltage should be no higher than 4.5 volts. Also make sure the cable is not kinked anywhere. How long have you had the new throttle body on? It can get sticky from the oil coming in through the valve cover breather from the fill cap. You may also want to get the air idle bypass plate that allows you to correct your idle without messing with the idle stop screw and TPS. Good luck I hope this helps a little.

thanx ill try that!

It says do not exceed 1.0 volts but really it should read 0.96V. Once you hit 0.96V the ECU thinks the engine is now under load, so you really want the TPS showing 0.9-0.95 at idle.
I personally would not fudge with the TPS...try and get the idle set with the throttle blade set screw. Use the TPS adjustment as a last resort.
