I was curious about the best place to look (repair/adjust,replace) to get my car through VA emissions. Failure was due to numbers, not visible rejection. Here is some background:
90 3.8 SC motor w 142K mi. No vacuum leaks as I sprayed points where vacuum leaks may have been present and no idle variation. Idles fine but car was sitting a while. I replaced Ign wires, pcv valve, air filter, plugs before test. One plug may have had oil on it. I am going to check it again since the car has been running for a while. After the failure I got a can of BG Fuel sys cleaner and removed a vac. hose from plenum and pulled cleaner into system slowly. Cats sound good (when you pound on the bottom) but one makes a little noise (very little) but may be grit in shield. Throttle body has slight snag in it when it starts to open.
Would posted numbers help from report?
No lights on in cluster assy.
When I pull the one plug, if it has oil again, I will try simple set of valve seals.
If no, where from there?
Cats
EGR
MAFS (mine was cleaned w/mafs cleaner and looks good b4 test)
MAP
O2's
I hate to willy nillie replace stuff.
Any ideas are appreciated.
