Hi all,
Iv had my95 WRX wagon off the road for a while so iv been replacing some vacuum hose etc in the meantime.
Anyway I fired her up this morning (first time for a while!) to find the revs hunting upto about 2000+ RPM then they went down to nearly bogging out..
So I did the ecu diag check to find the following codes..
CODE 23 (MAF) , iv already cleaned the maf sensor with solvent spray.
CODE 24 , And CODE 45..

Firstly, could all these codes be related , and could anybody offer advice on how to (hopefully ) Cure these issues..


Many Thanks in Advance!
Coddy!!

 

24 is Idle Control Valve may need a good clean with some brake/carb cleaner or it could be faulty
45 is the MAP sensor located on the driver side suspension turret I think they either work or don't work.

With the MAF though it would be best to test the voltage

 

Nice one for the heads up!
il give all those a try and hopefully she will idle alot smoother..if not back to the drawing board!

 

Make certain you have no vacuum leak. Mine sounded exactly as you're describing when I accidentally left a hose off.

 

thats another thing im thinknig..Only problem is, i cant get back to work on in for a few weeks but im going to have a few leads to follow now!
