Hey guys,
Can I anyone shed some light on a weird situation?
Canadian 2001 2.0l LX w. 180km: recently idles seems low, suddenly car seems to switch to low power (ecu adding fuel= lean condition?) and multi-cylinder misfires and starts whistling (sucking air through a straw) under load. Check codes(p300 only), clear code, runs well again, no misfire and plenty of power and whistling stops... for awhile, then it just happens all over again. Changed all 3 VTCS actuators, don't think its plugs, wires or coils because of you clear the code, it goes away. Could unmetered air be entering through some actuated valve somewhere controlled by ecu? Tried cleaning egr, not sure if I did it successfully, though.
Also noticed the ground connector mounted to the driver's strut tower is looking quite corroded, could this also be a possible culprit?
TL;DR - car stumbles suddenly with flashing cel, check + clear DTC, idle + power return to normal...returns after a few drive cycles, without any other codes.
Hoping for some kind, wise gurus to point me in a direction 'cause I'm stumped!
Sorry guys, I've never posted like this, I just don't know where to turn...
