Presuming duff MAF but opinions welcomed - update 1/10

After much use of the search function I'm pretty sure my MAF isn't functioning correctly.

Symptoms are an almost rev limiter like stutter at 4.5krpm in 2nd and then 3.5krpm in 3rd and 4th. Unplug the MAF however, and this disappears (but the injector light comes on).

Upon examination the MAF is virtually brand new - not a speck of dirt inside or outside.

So, my conclusion is new MAF. Or should I look elsewhere?

TIA.

(Oh and car is 71k, 2000 W 2.0 TS)

No personal experience of this but like you have read a lot of Threads on this and all of them support the symptoms you describe.

I would try and clean it even though it looks OK and then if that didn't work think that I would buy a new one, at least you'll know what the problem isn't !

Sorry I can't be more helpful, hopefully someone more expert will be along soon.

You say the MAF is nearly new.. Is the car running a standard airfilter of is it an aftermarket like a K&N? Also is the MAF a genuine Bosch or one off ebay?

Bosch MAF. Having just spoken to the previous owner it was replaced around 2 1/2 years ago - but has only covered about 7k since.

No idea about the air filter but I'm sure it's standard aftermarket not original ( I doubt "Fast Fit" of Dunstable would have used original parts).

Certainly sounds like MAF. I have just replaced mine after having flat spots at 4.3K and 3.3K. Flats spots gone and free reving now.

Aftermarket air filters might contaminate hot resistor in air flow in MAF and give burn on problems. Could try cleaning MAF per many threads, or cut to chase and replace it.

Hi, have the same problems on mine too. Does anyone have any links or info on how to remove and clean it? I have read other posts about what to buy from Maplins (IPA aerosol) but not 100% sure how to go about it and didnt want to take it apart first and break it or something!
Thanks :)

IPA aerosol will be fine.

I would just undo the clips and the wiring connector then spray the solvent through it. That will remove any oil contamination.

If you try poking anything in there like a cotton bud it is very easy to snap the element off. (as I found out :rolleyes: )

Check the rubber joints to make sure they haven't started to perish and let air in. A good application of duct tape should seal them for a while. Although from the sypmtoms it does sound like the MAF.

Took it all apart earlier and sprayed the IPA into the right places (thanks Jimmer & Symon). The rubber all appears in good condition but unfortunately it's the studs and nuts that have rusted solid. So now I have a sparkly clean MAF but an airbox in bits. Off to get a spare tomorrow morning.

I had the same problem with mine a couple of weeks ago and cleaned it twice, the second time giving the mirror a light wipe with a cotton bud aswell, after the second clean it is running spot on.

Ok, so with my new ghetto airbox and cleaned MAF the situation was better but not perfect. Onto ebay and a new one landed on my doorstep this morning for the princely sum of £22 delivered (sent Special D too!). Replacing the MAF took all of thirty seconds (I replaced the torx screws with phillips ones) and Hey Presto - new car.

The difference is amazing, the car is sooo responsive and free revving - I think I must have burned about 1/4 of a tank in the last half hour and the revs didn't dip below 4k. This is what I bought the GTV for:)

:thumbs: Good result then. Do you reckon that you got a genuine MAF at that price ?

Can you remove the GTV TS soon from your member car bit :)

Good luck with the MAF... there's been a few posts on here regarding the short lifespan of fleabay specials.

Definitely not - but as long as it does no harm I don't mind. I'll give the original Bosch one a thorough clean and try it again at the weekend. Doesn't hurt to have a working spare;)

Does anyone know the MAF P/No for a GTV V6 Turbo? I would like to check prices against the extortionate costing an independent specialist has given me over here in the Czech Republic....

According to the Bosch site it's:

Bosch 0 280 203 034

It also lists OE numbers:

ALFA ROMEO 195 64 11 013 00
ALFA ROMEO 6056 58 370
ALFA ROMEO 60579846
FIAT 60565837
FIAT 60579846
LANCIA 60565837
LANCIA 60579846

Doesn't really help you that much does it:lol:

As already answered in your thread.
The 2.0V6 Turbo didn't use a modern MAF sensor.
It used the older type that cost around £400 for a new one.
The tests used for the modern type do not apply.
