Thread: EMS thinks lean - why?

D'oh. I had read brake cleaner was ok and thought degreaser would be...and I didn't hold back with the spray! Will see how it is when I pick up from the airport tonight! I read you can't go aftermarket on the MAF... 26 pounds whole part.... versus just MAF insert but bosch at 100 pounds...

I hear you with the cheap MAF, but think of this, 2 tanks of premium fuel costs AUD275. You will waste more than that over a few months running rich/lean/badly

My advise is get a brand new legit Bosch MAF and keep yours as a spare. Good luck. Please report back.

Righto... will just get the insert as nothing wrong with the MAF body...and should keep it under customs NZD400. Will also post some figures of my OBD scanner. My fuel economy was pretty good on a long trip at 12.5L/100km. But when foot flat horrendous shudder and O2 lean bank faults...going to check connections etc as previously advised. Don't get shudder when foot flat in park so I suspect it is time for a front UJ replacement.

UJ slack is more evident with handbrake off and in Neutral, but chock the wheels first! Both front UJs can be replaced for AUD90 at home with a vice, circlip pliers, sockets to use as a press plug. And ~90 minutes. The yolk bolts are imperial too, for some reason IIRC.

Righto will give it a go in neutral with some clear track ahead of me....I looked up some how to videos and could probably do it... I think each UJ has 8 bolts so would have to find the UJs (front and rear are the same aren't they?) and 16 bolts - probably off Ebay

Bugger... just bought a Bosch F00C2G2032 instead of a F00C2G2029 MAF. Couple of places say 4% difference which the computer will adjust for.... bugger bugger bugger. Was NZD182 all up so not end of world stuff....will see how it goes. Also ordered new air filter (apparently the right one too).

Essentially a tube with a screw thread on one end, 'barbed' 'push on' hose fitting on the other and made of brass, not plastic like the original. The original one tends to become brittle from heat stress and then crack with age. It's not obvious to start with. Replace with one made of brass as described in previous post...will outlast the life of the vehicle

Here are the figures....very interesting. The 2 O2 sensors on 1 side are buggered as the voltage doesn't oscillate (wow listen to me). MAF looks ok?? May be a bit low...cos of O2 being out (right bank).





Also parked the car in neutral and revved the hell out of it...definite front vibration...little to the left maybe but sounds like prop shaft?
