Rough idle

[eddyvr4]

after recharging a flat battery, mines now stalling, when rapidly pulling up to a stop, and idling erratically. only done about 50kms since batt charge so il assume ECU is still relearning..... I didnt touch anything else. Maybe a clean of the idle controller wouldnt go astray. hope i can access it easily..

I found my car had lower idle after changing the air filter to a rampod k&n. I reckon it just needs a tuneup with a miniceptor.

Josh I think you'll find your problem is caused by erratic readings coming from the stock MAF sensor, discussed quite a bit in other threads. I'm unsure if you can tune this out with a piggyback unit or if you need a replacement ECU and different type of airflow sensor.

I know, but I was told a K&N Rampod was the right hi-flow filter to use for a mitsi honycomb MAF.

Also I didn't say it was rough... I just said it idled lower. I forgot to mention I threw on the rest of the aftermarket piping and new iridium sp's so could be any number of factors; including larger volume of air between AFM and manifold.
