The 4.3L V6 is known for idling high when the car has around 100,000 miles more or less. The cutting out could be a fuel filter or fouled/dirty spark plugs but more likely bad spark plug wires. Replacing them all should only run about $80 if you perform the work. Just make sure you get AC Delco spark plugs with a decent set of aftermarket plug wires and do those one at a time so they stay in the same order to avoid misfire/hesitation issues.

Idels high then low eventually cut out

combination of emissions controls and ignition control issues and mine which is a 91 does the same exact thing because the defrost controls cause the engine to rev up high then slow down.. I disconnected the ac compressor so it does not come on..mine has some vacuum issues that I have not corrected yet but as old and as many miles as is on it Im gonna leave it alone until the motor blows up smokes now and has over 300,000 miles on it.. rebuilt twice..5 head gaskets..6 timing belts and even when its really cold outside, it will start up when all my neighbors' cars wont..funny as heck..

Fast Idel Switch

When the computer senses the compressor is adding a load to the engine it bumps the idle up with the IAC valve.
There may be a low or high pressure switch on the compressor which cuts power to the clutch if the freon pressure is too high or too low.

Car idel high sometimes &cut off have to pump gas pattel&put in drive to go.

Could be that the fuel pump is failing. Have a pressure test run on it to see if this is your problem. It just takes a few seconds and is done under the hood. hope this helps and good luck....Please rate this post....

Idels high shifts hard and that is like every other time started put in new ecm and still have the issue

Your describing a vacume leak or a mis adjusted throttle body. Does it ever idel down? What engine is in it Desiel? If it's gas the AIS motor might be sticking or is bad. Does it run and is the check engine light on? are all the fluilds correct level? coolant level low can make the coolant senser lie about the temperture of the motor to the ecm and it'll command a high idel. Once the idel motor goes as high as it can it might be shicking and you can remove it and wash it off with carb spray and while it's out with the wire connected turn the key on and off with it in your hand and spray it with cleaner till it moves smoothly. With it retracted install it and try again, any vacume leak will make it idel fast. The trans mission will shift hard if the vacume line to it is off and it's on the back of the intake manifold and it goes to a modulater on the side of the trans. it can be off there too.

Front condenser fan ( only for the a/c) not commin on which in turn lets the system get hot. Hot means high pressure i a/cc system, high pressure trips the high pressure cut off switch.
