I dont know how to discribe this well. look intermitent too but more and more often. under mild acceleration from mid trottle, like if I want to accelerate but not pedal to the floor, the power come in form of a wave. Nothing rough, it is like a soft pulse. Like if I was slowly rocking my foot on the pedal (and I'm not). I have a chinese dice and vida and I have no codes. I've tried to monitor the pedal pot, the tcv (IPD) throttle body and MAF without any success to catch something. any suggestion to look at?
