other night my check engine light came on during idle. my RPM's jumped from 600 to almost 2000. check all vacuum lines and all are good. any suggestions??
get a diagonis machine, ...i dunno how much it cost..or just bring it to a local tuner shop, that happened to me two days after i got my v2 installed. turns out the temp. sensor was lose and it effected my rpm gauge aswell. but i took my back and they took care of it for free, i dunno if they wanna charge ur something to check it out..just depends on them.
