everytime i drive my 7 this seems to happen. everytime i stop at a stop sign or light the rpm drops like its supposed to but gets stuck at about 1,100 rpm. i can force the rpms down by letting out the clutch alittle to force it down and it stays down. wtf is this??

 

anyone?

 

Sticky throttle cable? Put your foot under the pedal and lift up on it next time.

 

nope. i checked all the obvious stuff, like throttle cable, linkage, etc. ive heard of some people talking about this before.

 

try blipping the throttle while in neutral when your idle gets stuck at a stop. That's not a fix, but at least you'll get your idle to settle where it's supposed to be. I'm not quite sure why the idle gets stuck like that.....anyone?

 

I had this problem on my 88 NA, I adjusted the TPS, (Throttle Position Sensor) with a voltmeter got it back into the right range at idle, but then found it wouldn't always reset all the way to 1K Ohms, getting stuck a little higher at times. (These TPS sensors are apparently notoriously finicky.)

I next lubed all the moving exterior throttle parts with WD-40, and worked the lubricant in by repeatedly running the throttle through it's range of motion with the engine off.

This seemed to do it. If you can't get 1K Ohm at rest and you don't get a smooth sweep throught the TPS range, you'll need to replace it.

You'll also want to adjust the idle set screw after getting the TPS dialed in.

Here's a good TPS adjustment DIY guide...

It could also be a timing issue, as discussed elsewhere in the forums.

 

My idle was sticking awhile back. I replaced the throttle cable and now it's fine. The old cable had rips in it.

 

i think your right. this sounds like the problem ive been having. ill try cleaning it up and ill see if i can somehow lube it up without getting alot of fluids on it. im gonna try to find another one too, thanks.
