codes p1320 and 300?? Ignition Misfire and malfuncution.... something along those lines cant remember the exact wording.

Right now my car is sputtering and riding rough unitl about 40mph. I have changed the plugs, put in fuel injector cleaner and iso heat (in case it was bad gas). Any input would be helpful.

The service light is on and sometimes it blinks also...

 

bump..........................

 

P1320 is the quarter mile racing error. It means your car isn't fast and furious anymore.

On a more serious note. Do the ecu self diagnostic with the check engine light. You will get the code in a different format. More users will be able to decode the "blink" format. You will find instructions on how to diag the ecu on the top of the forum.

My friend's WRX blinks the CEL when his car misfires so I assume when you see the CEL blink, a misfire had just happened.

Free bump..

 

Im getting a service light... and not a check engine light....

 

I dont think pre 99 cars have SEL lights so I dono anything about a SEL. Either way, run the ECU self diag and post up the results.
