3000rpm idle. WTF

Subject: 3000rpm idle. WTF June 7th 2009, 6:06 pm

Bought a ka24de to throw in my car, got was a douche and motor was complete shit so needed a headgasket.

Did the headgasket, got the car up and running smooth and took it out for a drive.

Drove around for about 10 minutes and car felt good so got on a tiny bit in 3rd then let off around 4000rpm and put the car back into neutral.

idle started to drop and when it got to 3000rpm it stayed there and wouldn't go any lower.

Not throttle related and I changed out the iacv and that didn't effect it.

Can't find a vacuum leak anywhere either.

Going to try and change out the maf and tps later and see if there is any change.

Another thing is sometimes I would start the car and it would idle kind of rough around 1500rpm, its kind of on and off when it does that which is why I don't think its a vacuum leak.

Any clue what it might be?

I'm sick of messing with this piece and just want to get my car back on the road driving.

if they guy was a douche, and the motor looked like or was total shit, why in hell did you buy it?

Motor looked fine, promised me everything was fine on it and once I got it in the car and running it was running on 3 cylinders due to a bad headgasket.

Hence the reason for him being a douche.

I'll just pull the motor, drive it back to Wisconsin and drop it on top of his hood.

So any ideas?

Car is popping like crazy now...

I already planned on it, my buddy is bring his over tomorrow.

I was thinking the injectors but it didn't stumble or anything like it had a bad injector while it idle's at 3000.

Anyone have a extra 5speed throttle body? Want to try changing out the tps.

its your maf for sure. if its running super rich and keeping the idle high, have you checked your ohms on your injectors and maf??

Hawt damn! Last few days I been having the same problem. But mine doesn't always do it, Like yesterday didn't idle high at all and today its almost at 3k
