Went to get the car smogged today. 130 miles to smog station, and I didn't baby it, so the cat was hot. Car drove great and boosts confidently.
Backstory:
Colleced this car in October, 1992 Volvo 740 Turbo Wagon. It wasn't running, 460k miles on odometer. Drove it 1400 miles home, took it apart, serviced most things. Head didn't come off engine this time, but I cleaned & resealed all else.
See smog results below.
My head scratcher: Last week, I flushed the oil after getting it running again. Didn't know then, but I had a hole in CBV, and put 30+ miles of "shakedown" driving on the car.....would that "pig rich" scenario have loaded up the oil with enough Hydro Carbons to fail my idle test?
At the smog shop, we pulled plugs, and they generally looked fine.
PS, after test I had a CEL 1-3-1 which I believe would be bad RPM signal. But the car never stalled....not even on the 130 mile trip home
What would throw off my hydro carbons at idle like that? Also not the "elevated" CO%
