Bringing this back yet again... I have an 04 foz XT and have been having AVCS issues with it but cant find help anywhere on them (a google search has lead me here). So here is the back round I have a completely random idle and mid range minor misfire (sometimes shows up on my AP under cylinder roughness sometimes doesnt). I've had a leak down and compression test the results came back fine. Car is stage 2 OTS map on my v3 AP (mods include dw200 pump, STI top mount, STI bpv, cobb SF intake, injen 3" catted dp, 3" N1 WRX cat back). So far I've replaced the fuel filters, fuel pump (dw200), fuel injectors, spark plugs, coil packs, maf, alternator, battery, AVCS Oil control valves, did a grounding kit, .5v alternator mod. When I did the new AVCS oil control valves it has helped the most the misfire seems much less frequent now. But on my AP under WOT I've noticed that AVCS in left seems sluggish (up to 4-5 degrees off between left/right side with some misfires). At idle the right side will stay at a solid 0 while with each misfire the left side will be jumping around from 0-3. Also on my AP I have been watching the OCV duty cycle at idle both stay at 9.4 but while cruising the left side will consistently stay about 1% higher than the right side so if the right side is at 46.3 the left side will be about 47.1ish. I'm pretty much at wits end with it and I feel like the AVCS left cam might be clogged/sticking but not a normal on/off sticking that most people experience (when I replaced the OCV on both sides the left one definitely looked way more gummed up). Does this sound about right? I'm considering replacing the left side AVCS cam gear to see if it finally fixes it once and for all but wanted some other opinions.
