Hey I got a 90 Integra and when I start the car it is idle'ing at 4000 RPM. What do you think it could be. I know I should go through trial and error ans check everything like sensors and ecu and what not but I just don't got time. Any one know what can cause it to idle like this? It doesn't do it jumpy it just stays at 4000, I give it gas and it goes back to 4 grand. Thanks
