I KNOW YOU HAVE HAD IT DONE, BUT THE EA THROTTLE ACTUATOR
HAS BEEN KNOWN TO BE UN-RELIABLE. I HAVE HAD 2 FAULTY UNITS BACK TO BACK NEW! LOW IDLES AND STALLING SEEM TO
BE THEIR FAULTS AS THE ELECTRIC MOTOR FOR THE IDLE AIR ADJUSTMENT CANNOT COMPENSATE FOR LOADED IDLE CONDITIONS FAST ENOUGH (A/C, P/S AT LOCK, ECT..)
BEFORE YOU GO POSTAL, MAYBE YOUR DEALER WOULD BE WILLING TO TEST FIT ON YOUR CAR. IT REALLY ONLY TAKES AROUND AN HOUR TO PUT IT IN AND A 3 DOLLAR GASKET.
SEEMS LIKE THEY OWE IT TO YOU AFTER ALL OF THIS!
GOOD LUCK!
