Title: hunting idle help please?
Post by: merlin2002 on August 06, 2011, 08:05:18 PM
Hi
 
Okay here we go...
 
Firstly info on car...
 
single Turbo
rats nest byebye
power FC
Aftermarket FPR
no O2 sensor and switched off via FC
 
Car idles fine untill warm then starts to hunt on idle...unplug idle stabilizer and idle is spot on!!
 
any ideas welcome for when I have another look tomorow
 
could it be just dirty isv? or idle screw or power fc needs to re-learn idle?
 
usefull info never had car running since I owned it till now, so no idea if problem was here pre rats nest removal which I have just done..car was mapped before this happend by, but not in my ownership.
 
Thanks
Rob

What are the TPS voltages on your commander? What\'s your idle set at on your PFC? Are your plugs in good condition? Make sure your idle screw under your elbow is screwed out 1/4-1/2 turn. Relearning your idle will wipe your map unless you have access to a dataloggit.
Getting the idle right with a PFC can sometimes be a job and other times it\'s a doddle, just takes a bit of perseverance.
