AFTER DRIVING ABOUT 15 MIN. CAR WOULD CUT OFF AND START UP RIGHT AWAY AND DRIVE AWHILE AND CUT OFF.I NOTICED THE BATT. VOLTAGE DROP BEFORE IT CUTS OFF AND THE RPM DROP AT THE SAME TIME.NO CODES STORED IN COMPUTER PARTS CHANGED- CRANKSHAFT SENSOR,MAF,TPS,IAC,INGITTION COIL MODELUE, FUEL INJECTORS, FUEL FILTER,.

 

Have you tried tu unplug your EGR valve ? I see you check all "standard" thing except for this one.

 

THANKS FORHELPING BUT I FOUND OUT THE 3.3 DOES NOT HAVE A EGR VALVE. I AM GOING TO TRY A FEW OTHER THINGS BEFORE I CHANGE THE ECU.
