from reading about the maf failing on my99 cars and having a pulsing problem with my car when runing on light throttle.i have checked the fault codes and got the following results.
2 long followed by3 short=23 MAF.followed by 1 long and 2 short.i understand the single long to be the start of a new code if this is corect what do the 2 short mean. any help would be appreciated.

 

I have left you a message I think, but I am keen to know how you are able to get the fault codes as I have a similar prob. AM@olchfa.org.uk

 

1 long and two short = code 12, which is the starter circuit mc1. Have you had problems with the starter motor or starter solenoid at any time in the past?

STi5300, if you have a classic shape car you can connect the two black plugs under the steering column and read any stored error events off the CEL light. If you have a new shape car you will need a Select Monitor, DeltaDash, SECS Monitor or similar.
More info here.

 

GM - is this the same on a jap wrx do you know??

cant find any black plugs

 

Cheers Greasemonkey thanks for the reply.I have not had any starting problems,but as the car is not my main mode af transport the battery can get low and when i start the car the alarm beeps usually after a cold/frosty night.I also now have a replacment maf.
