IDLE RPMs (again)

[chenson]

I've seen several discussions on various generations/engines regarding RPMs. I was wondering if some folks would mind volunteering what their IDLE RPM runs on their second Gens?

My 95 3.0 Manual runs about 1600RPM IDLE. I know that is way off.

1. What should it be for a healthy motor? I'm thinking based on what I'm reading in various posts it should be about half that...

2. What options do I have to address this? Several postings imply everything from a flathead screwdriver and a few beers to an actual engine servicing. I'm not the kind of guy to tear down a motor on a weekend but I'm not scared of jumping in with both feet either.

Any guidance would be appreciated. I'll be surfing my service manuals tonight....

800-950 is a healthy engine just about across the board. Flathead screw driver, and if you make it through an entire beer, I'd be worried . Idle is something I've fixed on the trail on my 22RE. The V6 will be different, but not by that much.

Thanks Awz. I'll post results tonight or in the morning.

Mine says 850 on the hood. Be sure to post results I'm at 1500 rpm and that after new wires brought it from 2000-2500

Sooo..... For better or for worse the throttle doesn't appear to need adjustment. If I let off the gas pedal the RPMs only drop down to 1500 or so. However, if I go rev the motor via the throttle and then release it the throttle drops to about 1k and I can gently push it down to about 900. Looks like the throttle just needs a little less resistance to retract completely. Going to read up in the service manuals tonight and tomorrow and mess with it Saturday.

PS: The previously unnoticed sticker on mine says 850 as well.

OK. It ended up being a combination of throttle stickiness and adjustment. Adjusting the idle did what it was supposed to do but it still was sticky. After some careful throttle disassembly and reassembly I'm running fine. Thanks all.

had the same problem..just bought a used 95 with 155,000 miles on it. Damn thing was idling at around 1500 rpms...

I screwed the idle adjustment screw all the way in..and it only took it down to about 1250 rpms...

I then noticed there is a nut adjustment on a stud , underneath the throttle cable on the rightside of the engine. Its hard to see and get to...but the stud hits this " black plastic thingy " ....I adjusted that nut and now im idling at about 900 rpms...

I think 800- 1100 rpms is perfect.
