Engine Performance problem
1990 Cabriolet 4 cyl Front Wheel Drive
Manual 95000 miles
I believe I caused this problem. After cleaning the intake/injector rail area to find an oil leak the car runs poorly once warm. After first starting it is fine. Once it hits running temp it runs rough at idle, smells like it is over fueling, spark plugs are damp and carboned (were not before this) It won't run over 2800 rpms under load. Accelerates poorly and lurches. If I unplug the coolant sender to the computer it doesn't idle as well but runs normal. Good power and no miss. The coolant sender Ohms appear to be close to spec. 200 ohm at normal temp. I also cleaned the throttle body area before this started.
