been trying to solve this dilemma.

at idle the revs seem to fluctuate up and down around 200 - 300 rpm. its really annoying and i know it cant be good.

so far i have tried resetting the ecu and cleaner the afm.

will i need a tune or is there some thing else i should try?

cheers

to test it, maybe do the spring tension up really tight, so that it can't open and see if the idle changes, otherwise check all other hose clamps etc are tight on any plumbing/piping that is after the air flow meter. make sure none are split either.

Make sure the bolt holding the ECU wires into the ECU is tightened securely. I had this problem and the bolt was loose. Incase you dont know, the ECU is found to the left of the passangers feet, under the plastic.

Also, check the AAC Valve.

Man I also have an idling problem - for 1.5 yrs still haven't solved it. Ive been through all the basics, these might help you, hasn't helped me .. like

Check all electrical contacts. squirt wd40 on all electrical contacts..

Could be the fuel presure regulator - do a swap .

clean aac valve. Swap with friend

clean, resolder afm

check for leaks - squirt carby clean on the hoses if the idle drops bingo. Soapy water should also do the trick but you will see bubbles instead.

make sure all sensors are working to spec. Do a search sould find what the sensors should read .

o2 sensors could be faulty.

BOV. I put a open atmo BOV and really screw my idle.. Took it off..

clean the injectors.. If you can take then out and get it ultrasonic cleaned.

check for fault codes

good luck

    • Heres another fitment photo. redrilled the pattern to 5x112, and threw my audi´s rims on. had to touch the upper control arms with grinder, because the "sharp corner" was sticking about 2-3mm on the tire path. i have the "fender lip" mostly cut off, otherwise these (too) would contact with it. 20x9.5 ET25 rear    265/30 20x8.5 ET20 front    255/30 they are temporary, and look too big for the chassis. searching for 19s to it.
    • From experience, it will come back to bite you haha.
    • Background: my BMW 225i hatchback (rebodied MINI/X1) came with 3x RE003 and 1x Goodyear Asymmetric something. The RE003 roared and slid around, the Goodyear side was quiet and grippy. Definitely my car was thrashed before it got sent to dealers. My brother also got RE003 all round on his old VA WRX STI, I wasn't impressed with them, car was loud so can't comment on noise. Anyway, Hankook stopped making/updating V12 Evo2. So bought S1 Evo3 runflats. Great daily duties tyre and not that harsh ride. Tyre reviews site/youtube rated them as best stopping in the rain and I believe them. Next set, Goodyear Asymmetric 5 non-RFT. It beat PS4 in tests and is like $100 cheaper, so put them on. Great tyre, more grip then S1 Evo3 but a tad noisier as expected, still rocking them. Next set I am looking to go runflats, probably the new Hankook Evo. Although the new Pirelli PZ5 did well in tyrereviews test. Or go Goodyear Asymmetric 6 which was top tyre last year. The V12 Evo2 on my gen5 Liberty GT wagon did great in cold condition (drove to snowy mountains for a day so my husky can feel his ancestor's roots). Super impressive performance for $120 each lol. Never skimp on tyres, brakes, suspension. There's old pics of my R31's crappy random brake pads bending in the caliper at Oran Park track day somewhere around here. Anyway, my 2 cents.
    • I said "Matlab clone". I could throw one onto one of my linux VMs. Probably only take 10 or 20 hours to sort out the dependencies, relearn how to use it, etc etc.
