Just got my car back.. the shop it was at it telling me because of my cam (TFS Stage 3 with 1.7's is .618/.632 lift) it is why my idle goes from like 1200 to 2k back to 1200 then to 2k then back down to idle at 1k. Also sometimes it hangs for awhile at 2k or a little more. Any suggestions? I havent cleaned my 10 pin connectors... going to do it now. But was wondering if the i cleaned the mass air sensor would that maybe help to?? Its the C&L 76mm with K&N filter on it.. heard the filter sometimes messes up the mass air sensor. Anyone have any suggestions?
