I have a B18C1 with CTR pistons, AEM COI, Whalbro fuel pump, DC header and Tanabe Exhaust. The car started out just idling and reving to 2000 to 2500rpms like it would hold for a sec then drop back down. Aftrer about 10 min it would stop. I took it to the track and after a run or too. Now it idles and revs to about 3000 and drop down then back up again constantly. I woke up this morning started it and it wont stop the idle. It pissing me off. I look like a dumb *** at a light.
I also have a little blow by rings are getting a little bad. Please help ASAP.

 

that sucks is it going all of the way down or is it just stuck at 3000? Check your throttle body to see if it is open at all or stuck. you can also check your idle control valve on the back of your manifold, that whont let in that much air but take it off and make sure that the little flipper is moving.

 

I fixed it hell yea. Thanks for the help though . I took the FITV out and fixed it, idles about 800 rpms now.
