I have a 1989 GL station wagon 1.8 Liters,SPFI, the problems is the car idles and suddenly it dies, was wondering if it conected to the timeing or a sensor going bad . when it is ideling the rpms goes up and down before it dies , hoping for some help here

Does the car have a good amount of gas in it?

 

 

 

Sorry, had to. :-p

Check the idle air control valve, sometimes these get stuck. might as well check your timing. Could be coolant temp sensor, these get corroded. There's more I'm not thinking of

check the engine codes a thte ecu described in USRM>miscellaneous. my buddy's car disd the grumbling idle and pulled a crank angel sensor code. it was fine but on some days it would not stat. he put the motor in another car and it died right away. replacing the distibutor fixed the problem

 

there are a lot of factors considering how the car runs but SPFI is very simple for fuel injection and the engine codes will hit the nail on the head with whats going on
