Re: Service Engine Soon Light Ghost!
Tommie – thank you for your vote of confidence.
jbclassis - Does the scanner show the system ever making it to closed loop operation?
The computer could have failed and the system is running off the back-up in the PROM (MEM-CAL)
As a test you could unplug the TPS and see if the computer is able to set a trouble code when there is a problem.
