Battlewagon Posted February 17, 2010 Share Posted February 17, 2010 A good friend of mine was driving around in his 2.5RS, everything was gravy until it stalled under load and now it won't idle. It had a CEL for upstream O2 sensor, so we replaced that but nothing. I thought it was an air issue, so I checked all the vaccum lines and found no leaks (at least to my knowledge). Then we thought it was a fuel issue. Replaced the fuel filter but no go. Now we either think it's the fuel pump or maybe the MAF. It starts, tries to idle and then stalls. What do you guys think?

lmdew Posted February 17, 2010 Share Posted February 17, 2010 It may have jumped timing! Fuel Pressure should be checked as well. Quote Link to comment Share on other sites More sharing options...
Durania Posted February 17, 2010 Share Posted February 17, 2010 It may have jumped timing! Fuel Pressure should be checked as well. That's actually not a bad idea. Quote Link to comment Share on other sites More sharing options...
Battlewagon Posted February 18, 2010 Author Share Posted February 18, 2010 Well, after checking the fuel pump and swapping fuel pressure regulators (got to love having Subaru parts laying in your garage), we went to the MAF. And that was it. I drove the car back to my friend's work and it was like butter. Quote Link to comment Share on other sites More sharing options...
Durania Posted February 18, 2010 Share Posted February 18, 2010 Good to hear. Got any pictures of it? I know its a 98 or 99 coupe from the MAF. Quote Link to comment Share on other sites More sharing options...
Battlewagon Posted February 18, 2010 Author Share Posted February 18, 2010 I don't have any pictures on me... I could get some. It's a black, 99 coupe on stock 6spokes. It's all stock and in really great shape; so much so that I plan on buying it after he goes back to an Acura. Quote Link to comment Share on other sites More sharing options...
