R33 Gtr Idling Problems

[georgeonboost]

Hi guys,

Seeing as i had no interest or replies in another section, i thought id try my luck in here!

Been on the forums for a while and just recently (last week) bought a R33 GTR v-spec with a few bolt ons and Power Fc. Love it to bits and im very happy with it.

After owning it for a week i came across my first problem. It had a slight intermittent stutter while cruising along but but your boot into it and it was boosting fine.

Then the next night, it started playing up and wouldn't idle and was hesitate and want to switch off while cruising at low speeds. I looked long and hard through the forums after finally getting the car home which was a pain, we changed the air flow meters as one was pretty rooted and the other looked like it had been replaced at some stage.

This fixed the intermittent stutter i was having while crusing but did not fix the idling issue. We tried to adjust the idle on the AAC but that didn't work as planned.

More research on the forums (thank god for SAU ), I took off the AAC and to my findings, it was pretty dirty and the spring which is controlled by the solenoid was very sticky. I gave it a clean out with carby cleaner as i didn't really have the time to strip it down into pieces like the DIY thread on here, put it back together and fired her up and set the idle up with the help of the hand controller to get the right revs and it was idling beautifully.

This morning cold start was a bit different. I let it warm up a bit, took off down the street and as i came to a complete stop, it stalled. Started up fine again and i was on my merry way. When the car was warmed up and everything was at operating temps, it was fine and never stalled.

Its got me stuffed. Is there another sensor that may be faulty or do i really need to strip the AAC down completely to clean it up? Is there a way to check for any error codes using the Power Fc?

Any help would be great.

Thanks,

George
