Hello everyone, I'm trying to find a solution to a long time issue that I cant seem to figure out. For some odd reason my isc position sensor "little box thing on top of the isc motor" is causing a surge issue when driving. I've gone through the entire assembly and it functions as it should on startup. When driving however between shift, the car seems to hold rpm and sometimes bounce around. Unplugging it seems to completely solve the issue. Anyone ever encounter this? And is there a part still in stock I could replace it with?

Hello everyone, Here again because I'm experiencing another odball issue that I can't seem to find a solution for. As stated above, my car "often in first gear" will hang the rpms from first to second for a good 3-4 seconds before they drop. If I just rev it up in neutral it works perfectly fine. I've tried adjusting the fuel settings with my maft, but the issue still seems to be persistant rich or not. Has anyone encountered this? could it be a vacuum leak or something fuel related? My isc nose switch functions good after rebuild. Logan

Hey, This is my first post but have been using the fourms for awhile to help with problems. But anyways, I'm trying to figure out why my isc only moves when the car cranks over. In the on position, it sits at .04 volts which indicates a problem. Out of options, I probed the harness connector with the ecu unplugged, and it appears that isc plunger ground is grounding to the mps signal wire. I looked at the electrical diagram and noticed those two wires go to the ecu without intersecting. Is the isc signal wire supposed to ground when the throttle closes?
