Hah, thank you guys!
OK, here is the thing. That engine has no PCV. Weird, hah! It uses an oil/air separator system.
No code, no check engine light.
Already poured a bottle of g2p into it last night. Will go to replace the air filter in a minute.
Now a small problem here though. The g2p bottle says I have to use up the current tank and then fill up with another tank before doing the retest. There's no way I can use up the current tank with my regular driving profile in 3 weeks. The FREE re-test is only valid in 10 calendar days. I happen to have a ~120 miles round-trip next weekend. So here is what I am doing. When I come back, do the test. Pass? great! Fail? wait until the current tank is empty, fill another tank, Italian tune-up and go for test. Still fail? Think about doing something else.
Any other thoughts? I think this is the best way, time and money wise.
BTW, in another forum, a guy with a High output version of this engine failed even after spending 1000 bucks on o2 sensor, cat, egr, plugs, wires, coils, maf sensor... Then he poured a bottle of g2p and it passed!
