Idle air control valve Check idle air control valve on throttle body. Mine had similer problems. A quick fix to get you going should be just unplug and remove spray w/ cleaner to get carbon off spring and cone shaft, reinstall. remember, this is just temporary. If cleaning helped, buy a new one soon. JMO

1993 Buick LeSabre surges and almost dies intermittently

Check fuel rail pressure.

Add fuel to beyond 1/2 tank.

A weak fuel pump do not like to ran low on gas.

When was the last gas filter and fuel pump change?

90-120,000 miles is the typical change out.

Fuel pump like to quit on a HOT day.

Test the pressure and see is it within specification.

Good luck

1988 Buick Lesabre: Power fluctuation

Remove all of the battery cables and clean them, replace both of the bolts. These cars will give trouble like this with dirty connections that you cannot see until you inspect and clean all three. A cam sensor is one of two things that tell the computer where #1 fireing is for starting car. They do not usually go bad, the magnet inside the engine will fall apart though and the engine light will stay on.

1997 jeep grand cherokee starts but wont idle on its own

It sounds as if you have a vacuum leak. It could be at the hose for the power brakes, pcv valve or the EGR Valve hose leaking. You may also have a bad fuel pressure regulator. Let me know if I can be of further assistance.
