Cadillac Repair/my 1985 Cadillac eldorado


So I bought the car about 3 months ago. It was parked for two years an I got it start up an run.. but when I went drive it. I put it in drive it died.. then started back up had no issue till I started try push gas pedal down go an it won't get up speed unless I keep push pedal down an then let off repeat.. can anybody help please.. o an I replaced fuel filter an old one was clogged


My first guess since you state fuel filter was clogged would be so is the tank and fuel pump.
The poor quality of gasoline we have these days turns to varnish when sitting. That is the purpose for the gasoline additive Stabil, if the car is going to sit for an extended amount of time. Check your filter again, it may be clogged again.
Your TBI could also be screwed up, but the source would be the fuel tank, which might have to be removed boiled out or replaced and a new fuel pump might be required.
The same symptom can come from a plugged catalytic converter, but since the filter was plugged I am betting on a tank issue with old gasoline.

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?
