I have recently replaced the clutch, carburator, fuel pump and some of the vacuum hose lines that had cracks leading to leaks in them. The car still starts up and dies almost immediately because it idles so low. It will not stay started and dies anytime you don't keep on the gas. I don't know where to find the other hoses I need because all of them I find have the same cracks in them. Is this even the problem in the first place. This all started because of bad gas we think and the spark plugs and gas tank have been changed. Please help!

A vacuum leak can cause this problem. Many mechanics will start the engine and spray starting fluid around the vacuum hoses. If there is a leak, the RPM's will raise. However, I avoid doing this because starting fluid can cause a fire if it hits something that is hot enough. If you try it, make sure to have a fire extinguisher near by.

Next, I can't remember if your car is fuel injected or has a carborator. It has been a while and around 1987 is when they all started changing. Let me know that. Also, check for an idle adjusting screw where the throttle is located on the carb or TB.

Let me know what you find.
