Scoobywagon Posted March 31, 2009 Share Posted March 31, 2009 Ok, so I need some help troubleshooting my 93 Legacy wagon. 2.2, AWD, 5-speed, 234k. When its cold, I can turn the key and it'll start right up. Once its warmed up, it wants to idle high. Mostly right around 2k, sometimes 3k. However, it will slow down after a moment and drop down to about 1k. If I put a load on it, say by giving it a little clutch, it will return to its high idle state for a while and then calm back down. If I turn it off, I can only restart it either by bump starting or by using the flood clear mode (WOT while on the starter). Once I get it started again, it will cough and sputter briefly, then idle high. Any thoughts? Thanks in advance. Link to comment Share on other sites More sharing options...

crockettbrat Posted March 31, 2009 Share Posted March 31, 2009 (edited) Are you getting a CEL code? This sounds like something that would set off the CEL. I would check the Throttle position sensor, and clean the Idle air control valve, and check the evap can purge valve. I had a similar problem with my ej brat, and my tps was not set right and my evap can purge valve needed to be replaced. Of course I had a CEL code to help me diagnose the problem.

Scoobywagon Posted March 31, 2009 Author Share Posted March 31, 2009 Yes, there is a CEL. Unfortunately for me, since this is an OBD I car, I don't have a particularly good way of pulling codes. So I figured I'd ask around just a bit and see what folks thought. Link to comment Share on other sites More sharing options...
crockettbrat Posted March 31, 2009 Share Posted March 31, 2009 Pulling the codes isnt difficult. Someone will chime in I'm sure, but iirc you connect the two black connectors with one wire each then turn on the ignition and the code will blink on the CEL. Long blinks first for the first number in the code and short blinks for the second number. It will give codes in sequencial order from lowest to highest and you should fix them in that order also because the lower codes being a problem can cause the higher codes. Pull the codes and you'll have your answer. The service manual for this can be found online in pdf and will have all the info you'll need to fix your problem. Good luck.
