Oh, well the car has been idle surging for a while now. It started back in September of last year. I replaced the throttle body, O2 sensor, MAF sensor, checked the PCV, checked for vacuum leaks, and in January it went back to normal. It idled good enough until my fuel system failed at Gridlife. I upgraded the injectors to DW 550's, a DW fuel pump, fuel rail, filter etc and the idle surging is back. The car refuses to learn the relearn procedure and one day, I had a crazy amount of hesitation on acceleration just out of nowhere.
Right now Im thinking its a MAP sensor issue, but I have replaced it and still nothing. I have had others in the community say its a tune issue, meaning Hondata has issues with OEM map sensors on NA cars, but upgrading to a 3 or 4 bar sensor would be a waste of money on a car thats not boosted.
