Answer 1

one thing you need to check real bad on it is the relay for the fuel pump,also the ignition switch on those car did cause problems a lot my uncle has one that did this,and we tried everything on it,we finally had to change the ignition switch,that was 3 months ago,and it hasn't stalled one time since then,you may have the same problem those cars had problem with ignition switches on them,those and the Oldsmobile's did the same thing,good luck on it,hope this helps.

Answer 2

Hmm, seem to be stuck on the throttle position sensor tonight and check your fuel pressure regulator.

If the timing has jumped or the camshaft gear teeth have stripped or worn away then when you take the distributor cap off the rotor will not spin or it'll jerk and stop and jerk and stop.

With the exception of Cadillac the GM cars have a aluminum and nylon camshaft gear. Some people say it is to make them run quieter but this makes no sense since Cadillac uses steel gears and the after market replacements are all steel gears. Go figure? The teeth on the aluminum/nylon camshaft gear wear away from hard driving and the chain eventually has nothing to bite on and then just slides over the cam timing gear.

Good Luck!

Answer 3

With a problem such as this one needs to go back to basics. There is a common troubleshooting tree that one must follow. First, remove all the spark plugs and examine individually. Check plugs for being fouled or soaked with oil or gasoline. Do a compression test. Check the timing belt/chain. Those procedures should disclose as to whether or not there is an internal engine problem and I would say that more than likely the valves are shot and that the vehicle needs a complete head job or possibly a timing belt. If the timing belt broke, at any point, you will need a head job because there is the possiblity that some of the valves will be bent because of the timing belt breaking.

Answer 4

Big help would be to pull the code, get in idea of the problem the pcm has picked up before going anywhere.

Just as a wild guess ....Sounds like Mass air flow problem or some type of intake leak. Little test is while it is at idle tap lightly on the Mass. sensor looking for an idle stumble or not.

Answer 5

Have the computer scanned by what you describe it sounds like a mass air flow sensor.GM products have a few characteristics that allow you to diagnose some of your problems without a scanner,if you suspect a component just disconnect it,this will not work on crank or cam sensor but will work on the rest.

Answer 6

I had a simalar prob....it was a sensor...the wires were melted

It would run for a bit then die(wires got hot and shorted out)
it would cool off and run for a block or two then die

great car and that was the only problem it was like 120$ at the mechanic

Answer 8

Crank position senser bad , Or is this one with the pickup in the distributer also gone bad. Has one or the other

Answer 9

you need a new timing chain...it has jumped time...or chain is so sloppy it is about to...
