Running well BUT....Idles at 2000rpm sometimes! - ZR-1 Net Registry Forums

Robm3 · 03-01-2009

Not sure if anyone's encountered this before but my LT5 has started idling rather highly at odd times.

I start it cold, no worries idles a touch fast (naturally) then settles down to a steady 1000rpm. If I go for a fast drive, sometimes it's okay, other times it'll keep reving at 1800-2000rpm and just surges up and down. Doesn't happen all the time though and when it is happening, if I pull up to a complete stop it calms itself down after about 30-60 seconds.

I replaced the Idle Valve control unit (little black thing hanging off the side of the air intake chamber) a few weeks back, perhaps it's something to do with the ECU calibrating the new sensor??

Any ideas??
