1986 2m4 5 speed

Hey all, since the clutch is now all dealt with and the alternator will be done by the weekend I have another question.

WHen I start the car the car will go at a high rpm of around 3000 to 3500 rpms, I can give a shot of gas and it will probably die back to about 1500 and that will not go lower than that. What could be the problem? THere is a vacuum hose plugged off that looked like it went into the throttle body(lack of a better word), but where it would attach looks like it is filled in. That is what it looks like to me, but I could be wrong.
Would this have anything to do with it and where can I get a schematic of it or even a picture of the right side(passenger side) of the throttle body to compare mine to?

Definitely sounds like a vac leak... here is the vacuum diagram...

Looks like to me it could be the EGR valve. Did that go into the throttle body and possiblly that is broke off, corroded off, etc?

Stop smoking pot in your car and the RPMs won't get high.

Sorry.

Hey, just found where my EGR valve was supposed to be and its not even there, they covered over the holes with some kind of welding and plugged the vacuum lines. So would a missing egr valve be the cause of my idling not correct? The mount that is there is probably not even sealed correctly.

A missing EGR is not an issue, if it the hole was properly closed off. Now, there is no real performance gain from removing EGR, but that is another issue

If it's not properly closed off?

Air could be getting into the mixture like a vac. leak.
