How Things Perform
Like a human’s heart, a car’s engine requires specialist care and normal checkups. If these don’t fix this, let me know so I can send you the complete wiring diagram of the cc circuit so you can verify the ground and energy supplies. I have a 1999 Cavalier and lately, I have an intermittent hesitation and misfiring and the check engine light will come on in the dash. Measuring the tps voltage applying ATS wiring diagram showed the tps is defective. Replaced the valve and also cleaned the passage tubing going to it. Immediately after resetting the code and road testing it, the code light went out.
