Cadillac Repair/Dts

Assuming it's the original engine and depending on the miles that are already on the engine the first thing I would check is the "intake flapper valve". That may be the correct name or not but it is located behind the power steering pump underneath the passenger side of the upper intake I do believe. They wear out after some time. More than likely, though, it's time for timing chains. There's 2, maybe 3  chains. One for each side of the engine. When they are replaced you'll need new chain tensioners too. Don't use the old ones even though they may look o.k. If you have a Chiltons manual the timing chain replacement procedure is do-able in your home garage/driveway except for one very important thing- you'll need a special puller for a pulley coming off the back side of one of the front camshafts. You have to have it but the dealerships won't sell it over the counter unless you're a ASC certified mechanic. It's a bummer but that's how it is or used to be. Why? Think about it. The dealership garage would make over a $1000.00 easily. Probably a lot more. You could go through a friend if he's certified  and save a lot of dough by fixing these yourself.

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?
