Yes, the ECM (Engine Control Module) and the PCM (Powertrain Control Module) are the same thing. Here is a picture of the ECM for a 1992 Cadillac DeVille Sedan: https://www.1aauto.com/images/items/items/KG/KG-1369/KG-1369-A.jpg.
Hello: On the passenger side, Behind the glove box on top of the heater case is the Body control module, From underneath (passenger side) along side of the Programmer is the Engine control module. There is no one main ECU. This information applies to the sedan devilles with the 4.9 engine
dee if the linkage is binding first, clean the throttle body and lubricate all moving parts if this doesn't solve it an accellerator cable may need replacing
The BLOWER MODULE is located on the A/C EVAPORATOR housing located UNDER THE HOOD passenger side firewall. Has 2 electrical connectors. Mounted with 4 screw bolts.Hope this helps
sounds like the ISC ( idle speed control ) motor is being told by the computer to extend or else its possibly binding. Located on the drivers side of the throttle body . Also check for binding aceelerator linkage. One other thing that might sound strange is check the floor mat by the gas pedal. Sometimes gets jammed.
you need to take glove box out. It's right behind three three 7mm bolts for the plastic piece that holds it in. two 10 mm nuts that hold it to the plastic piece. Should come right out with a little finessed force.
