ok i need your help, my 4 banger is missing alot, i though i fixed it but now when i first start the car its fine but once it warms up it starts missing. im thinking i need to replace the plugs which r in sad shape and the sparkplug wires.....but do u think the timing is off aswelll????

 

Might as well put a set of Autolites in her. They are cheap.

What year is it? It would help alot if we knew if it was Mass Air or not.

 

yea its a 1992

 

Try cleaning the MAF (Mass Air Flow Sensor).Remember to disconnect the battery too.

Could possibly be a O2 sensor, if you say it runs like poo once it's heated up.

 

the only problem with that is a replacement mass air sensor is couple hundred $$$$

 

You shouldnt have to buy a new one just clean it.

 

Yup, just take it out and spray the little sensors with some MAF cleaner from Napa.

Should cost $5 or less.

Look on google for instructions on cleaning it. Very simple
