Help understanding maf waveform
Help understanding maf waveform
I have a Renault Trafic that I have checked the maf on, I suspect it’s either a maf issue or sticking egr valve (down in power & no fault codes) the egr isn’t accessible without a lot of stripping, how can I determine using the maf waveform which is at fault? See attached waveforms for reference, they both start at idle and I snap the throttle wide open and back to idle again
Thanks
