April 13, 200421 yr 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.
April 14, 200421 yr Author EA82 - SPFI Skip sent me infor about the IAC valve. Thats getting cleaned tonight.
April 15, 200421 yr 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.
April 15, 200421 yr 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.
April 15, 200421 yr 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.

Nope, thats not the problem; good thought though, one of the things I did rule out. 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?
