Hi Jimmy,

The first problem I have with drivability problems is logistics. I am not at the vehicle to diagnose. However with this being said, I can give you a couple of ideas.
This could be a fuel system choked off from a plugged fuel filter. If it has never been changed and the low quality of gasoline we get these days, you may want to change any way because it is something you do need.Who knows, might even fix your problem as well.
A plugged catalytic converter can give you this problem as ell Being that one can't buy a test tube any longer which is just a pipe that replaces the converter. The exhaust at the engine would have to be taken loose feeding into the converter then driven to see if there is a power difference with this very loud car.
That i the two main things I can think of. You did not mention ifthe check engine or emissions light had come on for you.

Good luck and let me know how it works out.

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?
