Engine Performance problem
Cadillac Seville V8 Front Wheel Drive Automatic 208000 miles
Cadillac Seville. The car was running great when I parked it but it was using too much gas. Started it this morning and the car is running a bit rough at all speeds but is not a dead miss. The car will not go over 50 MPH and it smells hot, but the temp guage is normal and I am not losing coolant. I am not getting any error codes. When I try to accelerate the transmission hits hard. All fluid levels are normal. - History - I recently changed out the TCP and the ICM. Backed off the ICM, through the computer, to set the TCP at +.2. The ICM has not controlled the idle speed well and the RPM at idle is usually too high. - Question - What will cause the car to have no power, smell hot and yet not be running hot? Vacuum leak? Dwell ( dwell and timing is computer controlled )? Any suggestions. Thanks.
have the same problem?
