Hi all
Does anyone have scope waveforms saved for this system? In particular the MAF, MAP,3rd injector reference etc.
This vehicle has come to me after having a MAF fitted by another garage that has made no difference to the fault which is a momentary misfire when started from cold and an occasional glitch under hard acceleration.
The MAF shows 2.25v at idle rising to 4.75v at full speed and i feel this is not correct and suspect a cheap after-market sensor has been fitted.
Any waveforms from a known good component would be appreciated so that even if my suspicions are incorrect i can test the other sensors.
Thanks for your time
