ive just fitted a fmic to my 96 WRX before a simtek being fitted next month and i took it out for a quick spin to charge the battery (been on the drive for over a month whilst i refit the kitchen

when i started it it was idling at 2k revs and when i got back it was really lumpy at about 1400 and the cel was on

i think i know the answer to this one (remap) but has anyone else had this problem without a remap being done?

 

Sounds like a air leak maybe?

 

Nothing to do with mapping, more likey the fitting of the cooler.
Check for air leaks and also confirm the cell code.

 

ok just checked the cel code and its showing 24 which i gather is some sort of idle control system malfunction
can someone point me in the direction of the idle control valve and/or if theres any other parts i need to check
can i clean it in some way to see if that works?
