Hi i have just fitted a new mass air flow sensor to my car and is running better but still not right i brought a Bosch 1 i seen someone write on here before it took around 150mike before there car was running correctly again is this correct?
I had the MAF on my corsa around 6 months ago. The only thing we did was clear/reset the ECU afterwards. Its also worth checking the carbon build up around the carb, as mine was heavily soiled. Give it a good clean, tighten everything up, reset the ECU, and you should be good to go mate
Cheers for replys there was no elm light on in the first place but had all signs of maf so i changed it after people telling me on here that's what it would be so i out a genuine Bosch 1 on its a tad better but still not right from 20mph but picks back up at around 40mph like power just comes back in
This has been playing on my mind all afternoon, im trying to remember what finally solved mine
To be honest, the only things i would check at this stage is everything is done up tight, like the clamps around the MAF. Its also worth checking that the airbox lid is still on securely. I managed to snap the clips off of mine whilst changing the MAF.
I wouldn't have thought it was the spark plugs, because i think they would cause problems across the board.
Completely disconnect your battery over night, and reconnect in the morning. I heard that is the easiest way to reset the ECU
Beast1, I would get a picture but all of them are blocked at work.
Google 'Corsa b Maf' and click 'images' you will see that the maf is a tube (uses the two clips to hold it in place), then there is a connector, this simply clips into the wiring loom. It's just a case of uncliping the wires, undoing the metal clips, and removing the MAF.
Lg, you didn't touch the sensor inside the maf tubing when fitting it did you? i've heard this can affect the sensor readings.
