Engine Performance problem
1983 Cadillac Deville V8 Two Wheel Drive Automatic 117000 miles
I've been having what seems to be fuel issues, and have codes returned that are 38, 52, 33, and 44.
Can't pinpoint the problem and have replaced the fuel pressure regulator and MAP sensor. Spark plugs look fine. Can't seem to locate the O2 sensor, as my repair manual is general - " upstream of the catalytic converter.&Quot; Where is the bloody thing?
The engine doesn't stall, per say, but has a slow, hesitant start and the service engine soon light comes on intermittently, even at high gears.
Thanks so much for your time!
