I just bought a 1991 Cadillac Touring Coupe. I'm getting the following codes:
F32 - BCM-ECM Data Problem
E19 - Shorted Fuel Pump Feedback Signal
E21 - Shorted TPS Signal
E98 - High RPM P/N to D/R in ISC Range
This comes along with low speed stalls, hard starts, tranny slippage, speedometer going wild. It seems to go away when the car warms up, and when I take it on the highway it seems fine.
Any help would be great,
