Well I am nearing the point of desperation, i.e. throwing parts at the darn thing, so hopefully someone has a more intelligent solution.
Replaced the purge valve and every rubber vacuum line near the engine but still no luck. Does anyone know if the main engine computer (what connects to the upper harness) could have any role in the idle and cruise control?
I know this car was driven for many many years w/ the eco junk harness, so possible that computer is burnt. Otherwise, thinking the secondhand throttle or EGas/TLLR modules could actually be bad. Running out of options at this point so any suggestions are welcome
