Question
i have a 1991 cadillac eldorado that keeps cutting off while im driving or sitting at a light. i would have to let it sit for about 2 hours before being able to drive it again. im okay maybe at short distances. can you tell me why.i first was told i needed a valve cover gasket then i was told that i needed a distributor

Answer
Hello,

I can't see how a valve cover gasket that prevents oil from leaking from the valve cover would have anything to do with the running or not running.
The distributor does what it says, it distributes spark, however a distributor problem generally will not give you the symptoms you are referring to.
The biggest problem is that everyone has an opinion as to what may or may not be causing a drivability problem. The thing about it, is more often that not, the information is totally wrong and in some cases when people use this information to fix their car, they commonly ust replaced a perfectly good part and still have the same problem. Free advice which costs nothing is worth just that, nothing.

This economy sucks and I realize people are doing everything they can to repair their car by themselves. I appreciate that. There are far to many things that can be causing your symptom. It can be fuel delivery electric or electronic and guessing will cost you frustration and money.
Your description would lead me to think the problem is electronic, that once heated up, stalls the engine which could be a module of some sort under the hood. It could also be a computer problem. Whatever you do DON'T go to a dealer. Find a service center in your area.
The nice thing is that the problem with diagnostic equipment can be detected easy enough because this is easy to replicate for a technician.

You may pay an hour for diagnostic time, but the you know exactly what the problem is and it can be repaired.

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?
