Ok, car has been running RICH for the past few months. Finally got around to working on it today. I did the following:
Replaced plugs (AC CR43TS gapped at .035")
Cleaned, dried and reoiled K&N Air filter and both valve cover breathers
Oil change
Now, my oil smelled of gas PRETTY BAD! Plugs didn't look too bad but they didn't look good. The car has been running fine in the morning going to work, on way home (about half way home; 10 min) sitting in stop and go, it started cutting out. Almost the same feeling as a bad MAF. Ran fine on NO boost but once boost hit it just sputtered. Again, this was only on the way home. In the morning I can run 18lbs of boost just fine.
After working on the car it idles rough and seems to break up as I rev it and acts the same while driving. I checked spark plug wires and they are on in correct order. When I first start the car it starts to idle at 2000 rpm and slowly backs down to 700-800 rpm.
Scan Data:
O2 Volts - 300-800 at idle
O2 Cross Counts - Starts at 8 and slowly works up to 200 and the falls back to 8?
TPS - .39 at idle; 4.59 at WOT
MAF - 5 at idle
INT - 123-135
BLM - 120
Knock - 0
Idle Air Meter - 56 to 57 steps
Temp - 169.2 f
Idle - 700-700 rpm
Any ideads? I'm thinking my O2 may be shot. Usually it jumps around at idle but seems to have lesser of a range to jump around in. Car does not run well enough for me to get any WOT #'s. Any help will be appreciated!!
