Help - Revving Too High
Finally finished working on adding some twin turbos to my 964, appear to have resolved all the oil leaks, but the car is revving at 4000PM. Is it that I have some line incorrectly hooked up or could it just be an idle screw issue?
Thanks biggles

My car revs way past 4000 rpms, so I'm not clear on what your issue is. You need to be just a tad more descriptive. Are you referring to 4000 rpm at idle? If so....holy crap, that's just a little bit excessive.

Mark
Yes - 4000 at idle. It has been sitting for almost a year, so I would figure about 1200 - 1500 until warmed up and then 900 - 1000. Thanks! |

I have not adjusted the idle and the O2sensor is not hooked up. New exhaust, so I need to get the bungs welded. Will try to adjust the idle, and see the effect.
Thanks |

Yesterday after the car was warm I decided to disconnect my 02 sensor to see what would happen. When I restarted the car the idle was way up and the engine was running way lean. I didn't try it on a cold engine. Just a FYI

Think I may have resolved my problem. Just changed out the after market chip and reinstalled the old chip and she idled at about 1200. Hopefully, tomorrow after work, I can let it run longer and see how it works.
Thanks for the feedback. |
