Hi,
I have a '94 st202 Jap Import. On idle the revs are up and down as far as 1500rpm and as low as 500rpm. I took out the K&N and installed a standard air box with new filter. It has had a full service and all new servicable parts changed but it is still doing it. There is no loss of power and there is no misfire. I suspect that there is a pipe sucking in air somewhere still unable to locate it. Had a few mechanics looked at it and all are stumped. Am I to live with it or can this be fixed. Any information and advice gratefully received. Thanks Clayton |

Check your vacuum lines for cracks, or it sounds like the idle air control valve is all gunked up
