Ok, when was last tune up? Worn Plugs, Corrossion on the Electrode in the Distributer Cap, Vacuum Leaks can all cause your problem.
Is the engine light on? I f so will need to pull codes...
1.Access the ECU and position it for observing the diodes.
2.If the engine does not run, turn the key on and proceed to step #4.
3.Start the engine and warm it to operating temperature then idle.
4.Turn the diagnostic mode selector on the ECU fully clockwise until both diodes flash 3 times then turn the selector fully counterclockwise. The ECCS system is now in mode 3.
Post Codes for further info...
