Hey guys.

I have a weird problem with my car. It is a 1994 2.2 VTEC import.
When my engine is tunning and i am at a stop near a traffic light or whatever I notce that my rev meter rises slightly to the 1000RPM and drops down to 500 RPM.
It doe snot really go to 0 and stay there?

Any one had and similar problems and know how to help?
thanks

 

Maybe the throttle body and I.A.C valve need to be cleaned. You may also have a vacuum leak.

 

yup sounds like a vacuum leak to check all your lines on the valve cover manifold

 

what is the engine manifold? and what si the firewall?

sorry but I do not know the technical terms, but do have some mechanical skills!

If you guys give me a description and what to do I should figure it out.

thanks
