CM871 poor power and fuel econ

DEMANDATE PROGRAMMING...
first and foremost, assume the delete program is bad. Pull a copy of the program out of the engine and e-mail it to me for a proper review.



next, if the enigne does not shut off right away when the keyswitch is turned of.. .. then it is a leaking fuelling (metering) actuator....or less common, but it can also be a timing actuator + a leaky injector.

next, if the metering actuators were going bad.. something caused it. YOu did not mention anyone doing a proper injector leak test, so that is the next step as well.
