Hi,
I'm using MS2 v3 with edis4 ignition on my 4age 16v engine.
I fairly tune my engine using LC-1 with the help of megalog viewer.
I find the stable idling at 13.3 afr

My problem now is when idle at 800rpm then suddenly press the accelerator and release the pedal, my rpm dips to 500rpm and then suddenly return back to 800rpm .

any suggestion how to lessen or eliminate the rpm dipping ?


thanks

Check your AFR - what's it doing when this happens?

I will post my datalog files later, i'll have to get an new bosch o2 sensor cause mine is broken
