thanks guys... the O2 sensor was replaced by a shop the last time it
failed (in july 04) and it failed with harder NOX and a higher amount
of HC, though it was still in the legal limit....

no ECU codes...

might install a magnaflow direct fit replacement, if i can get them to
confirm it is california smog/noise legal...

sort of stumped cause i have another inspection coming up in june or
july.... i am now using the proper OEM NGK plugs, did some intake
cleaner throught the booster, idles much better, drives smoother...
cleaned a lot of carbon off the pistons.

you guys know what effect a PCV catch can would have on emissions? i
know it wouldnt do squat on NOX, thats temp related....but any others?
