Cold Start R33 Gts-t

[PJF]

Hi there,

I have a standard, bar cat-back, 96 R33 GTS-t and while driving it cold the revs fluctuate between 2 and 3 grand when I put my foot on the clutch and accelerates when I take my foot off the throttle. Once it's warm it fine. Has anyone ever had this problem?

just be the cold start feature. Just dumps more fuel in and brings the revs up a bit to warm the car up. Thats wat it sounds like anyway

Yeah, mine does this too... best to just let the car sit for a little while before you take off, maybe 20 seconds at least.

Mine doesn't fluctuate THAT high though... it'll drop to about 1500 after taking my foot off gas (in neutral) for a couple of seconds then down to about 800.

yeah don't think it should be going anywhere near 2000rpm at idle. i'd say that your IAC is getting a little bit sticky, and your idle screw needs a bit of adjustment.

might also be worth cleaning your throttle body.

Cheers guys, think I will clean my throttle body. The problem has been getting progressively worse.
