Rpm dips low..

[dsm03]

Let me know if anyone can help me out and figure this one...

When I ddrive my car and it is usually just the initial step when I depress the cluth pedal/clutch in my rpm just dips all the way down whether I just clutch in to slow down or ready to upshift. Doesnt seem to wanna die or anything though.. Im stumped, the sensors have been checked and they seem ok unless its been over looked or something..

please and thanks ahead of time!!

any cel? check isc

 

[dsm03]

There is a CEL, although its for one of my O2 sensors on the exhaust. My CEL has been on since day one but the car never did what its been doing when I first got the car..

 

[nongthep]

You should call a local shop and find out

No shop in this damn city deals with dsm's, If I take it anywhere all they tell me is how bad of a car dsm's are.. makes me angry at least try to direct me elsewhere instead of critisize.. grr!!

Sure Have.. Only place that I had leaking was throttle body shaft, replaced throttle body.

And intercooler piping, replaced with Greddy aftermarket pipes.

As long as you have access to a multimeter, you should be able to test this.
