when starting the car after sitting for a while, the cold start will take kick the tach to almost 5k stay there for 1-3 minutes instead of the 30sec or so it should then drop down around 2k and start jumping, 2k-4k. it will continue to cycle like this for up to 15 minutes. i've found the only wy to get it to stop is fight it to hold a steady rpm with my foot. once i do that it will drop to its normal idle.

 

slow down guys, not too many answers at once now.

Have you adjusted your cold start idle screw? I'm not talking about the cam itself. (You may already know, but...) there is a screw just to the left of the cam screw (sitting in car).

could be the vacuum solenoid - but then again when mine did this everyone was suggesting the vacuum solenoid and it turned out the ports were binding - too much air coming in ment the EGI computer assumed the revs were being underreported, so it pulsed the throttle in an effort to find the 800 RPM idle it was looking for.

In my case cleaning the aux ports worked. In the case of the solenoid, try to find a used one (new ones are a few hundred bucks!)

 

there was a leak in a gasket on the upper part of the intake and the high idle screw needed adjusting. friends car and she took it to a shop that did a bunch of stupid **** (rotary shop at that) and then they finally fixed it right after causing more problems.

 

Hey Jeremy... I kind of revised your signiture image. Tell me what you think. ; )

 

lol, i'm not sure if the late sesshu would appreciate a 1st gen ripping up his painting or not.

 

I don't think he would mind as long as it was a 1st gen. No 2nd gens though... Those are for goobers.

and tell Jen that I will take her SE worries away if she would only give me the keys.

 

i'll talk her into trading that se for my 79, how about that, lol. aren't you supposed to be spending quality time w/ the wife right now?

 

QT spent...

Hey, if Jen wants to trade, I'll do it, but the 79 is still prettier.

 

i tried. she just doesn't get it, lol.
