No engine fan on constantly, idle is sweet. BUT now after decel coming to a stop it cant seem to find idle. At first i thought the ECU was learning but it hasnt got better. It almost dies and then picks up 3-4 times until it slowly works itself out and then its fine.. I think you might be onto something el freddo.. It cant be vacuum because i got my guage hooked up and its fine at 20hg/m? (side note: does anyone know how vacuum on the EJ should behave?)
Guess I'll check out the IAC and TPS!
