Cadillac Repair/1992 Cadillac Deville


Hi rob it has been awhile. I am having an accleration problem with my 1992 Cadillac Deville. When I try to get on the interstate and I floor it the rpms raise I can hear the motor reving but I get no accleration. The car does not increase MPH. I can hit the gas going 40 and I have to lift my foot to get it to acclerate a little. Not sure if it is a fuel problem or what. I had the neutral safety switch come on twice awhile back ago and it hasn't been on in awhile. Not sure if this could have any affect. Thanks.

I believe I answered this question in a later question, because I was going to say from the description, it sounded like the transmission was slipping.
I received a question on the same type of vehicle yesterday asking about pulling the transmission pan off to drop the fluid, because the fluid was brown and smelled burned.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
