mr.radon Posted April 13, 2004 Share Posted April 13, 2004 HELPPPPP Well I've gotten about 2K miles on the new 5SPD -D/R tranny I put in my "new" 88 GL Wagon. However, I still have not been able to kill the idle gremlin living under the hood. A few days ago I thought I had it when I pulled the full sized spare and saw it rubbed a crack in my new vac line. I replaced it, nothing; just as bad as before. All the vac lines have been replaced and still I have this problem: Start car, idle goes to 2.5K. As car warms up idle lowers just a bit. After driving for a little time the idle will come down to 800RPM just fine. Now lets say I'm in stop and go traffic I idle along, slow down to where the tach is at 700RPM, push in the clutch, whammo idles at 3.5K for a few minutes. Get up to highway speed, push in clutch, idles at 800RPM. Help, my head hurts from: I'm good at following instructions. Where do I start with the trouble shooting. The Haynes and other manuals I have, never mention anything about idle problems. Link to comment Share on other sites More sharing options...

Dave643 Posted April 15, 2004 Share Posted April 15, 2004 now, when we are talking about cleaning the IAC valve, does it involve more then the little gold cylinder (behind the power steering reservoir)? I think mine is bad but I'm not sure what to clean. Link to comment Share on other sites More sharing options...
greggbrat Posted April 15, 2004 Share Posted April 15, 2004 Sounds like something is possibly sticking. Does this scenario happen? You are sitting at a stop light in neutral with the clutch pedal not pushed in. The motor is idling at 700 RPM. Then you push in the clutch and the idle raises to 3500 RPM. If this is the case then something in your clutch linkage is probably hitting the gas pedal linkage. Link to comment Share on other sites More sharing options...
Partsman Posted April 15, 2004 Share Posted April 15, 2004 Try this manual: http://www.finleyweb.net/docs/SubaruEA82-ServiceManualPart1.pdf http://www.finleyweb.net/docs/SubaruEA82-ServiceManualPart2.pdf Look at tests for IAC valve and circuit. Do you have a code set? I doubt it's a problem with linkages physically touching if it only revs to 3.5k. Link to comment Share on other sites More sharing options...

I chug along with the clutch in at idle, you know stop and go, when you are forced to puch the clutch in because the engine would sputter the RPM's go way, way up and very, very, very slowly come back down to normal. There is nothing binding the throttle pedal nor clutch. I don't get to check anything last night, had to plant my flower bed. Will do it this weekend when I get some free time.

I looked and looked, didn't see a section that deals with this. What section, what page?Codes as in read out the fault code? Damn, didn't think of that. Good idea. The IAC valve has a code?

greggbrat Posted April 16, 2004 Share Posted April 16, 2004 Did this problem exist before you did the tranny swap? Link to comment Share on other sites More sharing options...
