high rev

Recommended Posts

Mine does it when it doesn't start fast enough (long cranking time).

I figure the injectors put more gas in during the long crank, and a few seconds of higher RPM's are the result.


I've also had (Renix) XJ's that do this for 20-30 seconds, or more after starting, and that usually tells me to check out the idle air control (solenoid on the side of the throttle body).


They get gunked up & crappy, a good cleaning works wonders. :yes:
