Hello!Is the check engine light on? Are there any codes in the computer? Does the engine die when coming to a stop or when driving at steady speeds?When was the last time you have had a tune up done?
no check engine light
no codes on the computer
it dies both when coming to a stop and steady speeds
Ok.. the most common cause of this condition(s) you are having is either a bad camshaft position sensor or a bad crankshaft position sensor. The computer uses both of these sensors to determine thee engine speed and thus control the fuel and ignition timing. If one of these sensors go bad (even intermittently) it can cause this sort of problem you are having. Also, check the distributor sync. If it is out of sync, (turned too much in either direction) it will cause this problem too. I hope this helps!

how do i check the distributer sync?
and no i havent gotten it a tune up
To check the distributor sync just turn the engine until the balancer is lined up at TDC and at the same time the trailing edge of the metal part of the rotor needs to be 0.020" past the #1 terminal in the cap in the distributor. Adjust as needed.
