Hi,

I have found it quite amazing that I have had the ability to fix problems with vehicles sometimes thousands of miles away without seeing them. Here is another situation that I can assist you with.
What I believe you have is a fraid accelerator cable.
Stranded wire fits inside a plastic tube. Over time, the wire frays and binds outside the plastic tube. These cables are common in these vehicles. They are also used for shifting the transmission.
The correction is to remove the cable assembly from the the accelerator pedal in the rear and any attaching components. Open hood Remove the grommet in the firewall. Remove the air intake ducting. Usually a couple of clips on each side. At the throttle, you will see where the cable connects.You will see a square piece of plastic with you cable slid into a bracket. With a screwdriver slide it outward. Reinstall the cable the way you removed. Your noise will be gone and the engine should be more responsive.
Good luck!

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?
