WRX cylinder misfiring...HELP!


Recommended Posts

OK. I am beginning to think this is a stupid question...but what the heck..

 

I own a 2002 WRX wagon. Love the car - but the engine light has been working overtime. Originally, I had it serviced and was told cylinder 1 C had misfired. They (sub. service techs) re-set the computer...but, every 250-300 miles it likes to come on again. This has been ongoing ... at least a half dozen times - over the past 6 months. I am starting to get really irritated :-\ - never sure if the light means really serious problems - or, just the darn cylinder again. Is this car a lemon? Why do the techs keep re-setting it...only to have the light re-appear? They told me last time (this past friday) that it was too soon to replace spark plugs. As you may have guessed I am a relative Subaru rookie - so, I need to know how to speak knowledgably to the service people (sometime I feel like they are just doing the minimum to get a stupid woman out of they service area). Anyone else having these problems with their WRX? Looking for some advice...with only about 6000 miles left on my warrenty - I am concerned this could be an indicator of bigger problems. Any help would be appreciated...

If they have checked everything and it checks out ok . Then it may be a fasle indication by the ECM , there is an updated ECM for early production 2002 WRX for false missfire codes

Get the dealer to check with SOA

That is actually a campaign for that. Will cost nothing in theory for the dealer to do it. They send the ECU off to get it reflashed and you should have a turn-a-round of 4 days at MAX...could have back in 2 days tho.

Hey! Thanks to all who replied to my earlier post. :clap:

As it happened I was visiting family 300+ miles from home. The drive through mountains with the glaring*check engine* light was not a soothing sight. Spent many a minutes considering trading it in for another model - just love this car! So, I want to give it one more try...I plan to visit the dealership first thing tomorrow. Will let y'all know the results...stay tuned!
