Hey guys,
my idle drops when my fans kick in to cool things down while im idling at the lights. Its kind of a pain it idles a little rough between 500-600 with fans on. Driving around its fine, i guess it just needs a tune up or something?

Auto or manual? I put my revs up another 50 - 100 just for the fans. Was idling at about 500 and being auto it wasnt enough, stalled now and then, bit rough etc. This all before my current probs of course lol.

Makes sense to be, is this an expensive part to replace? I might just ignore it until i have to fix it

Just raise the idle slightly in the normal conditions to compensate for it? nothing huge
