Jonpro03 Posted August 6, 2009 Report Share Posted August 6, 2009 When I first start the turbo in the morning, it idles terribly. Almost sound like its missing a cylinder. Once I get cruising, the idle raises. If i keep my foot off of the accelerator Ill still accelerate. If i put it in neutral while cruising, the rpms will jump to about 4k (guesstimating cause my tach reads high). Then when I come to a stop, the rpms will drop suddenly to about 800 (guesstimation). I thought it might be the IAC so I unplugged it when it was idling right and drove it, the rpms still climbed to about 4k cruising in neutral. Any ideas? Would it be because the speed sensor in my car is reading high? (I never swapped them when I did the tranny swap, it reads about 10-15mph high) Thanks Jon Quote Link to comment Share on other sites More sharing options...

(I never swapped them when I did the tranny swap, it reads about 10-15mph high) Is the speedometer actually reading high(going by the HUD...as the speedometers are horribly inaccurate)?

Jonpro03 Posted August 10, 2009 Author Report Share Posted August 10, 2009 No it actually reads high on the hud, the needle is off another 2-3mph too. Quote Link to comment Share on other sites More sharing options...
