Whats up everybody.........I have a question that Im hoping someone can help me out with. I just got done putting in the engine that I got for my VE5 . I started it up and everything went fine, but I noticed that it was surging pretty bad . It surges to about 2500 or so and then goes back down to normal idle revs.......Im sure you guys know the deal.
My question is can anybody direct me as to what the problem might be. Im hoping that this was addresed before and there was a solution. My guess is its a vacuum leak or something, or even an IAC valve problem. My MAF seems to be okay, and all my vacuum lines appear to be fine also. I know its prolly something simple that I just keep lookin past, but I really want to get this thing goin so I can start rockin a VE5 so if anybody can help me out I would really appreciate it. Thanks Errrybody

 

anybody?...............Beuler.....Beuler.......... ...................

 

vacume leak sounds like a good start

 

IACV would be another guess. I am pretty sure that's what my problem is. My idle stays high and surges when it's cold. I just haven't bothered with it. Too busy with other stuff.

 

So does your surging go away when it the engine gets warm????

 

does anybody happen to have a pic of the throttle body area so that I can reference that when looking at my engine. This diagram from autozone.com is a bit comfusin to me for some reason. thanks
