2.0 Petrol Maf

[ricaxy]

My Galaxy was running rough as a dog, after i disconnected the MAF.. hey presto runs fine. it was OK.

 

Still, anyone got any ideas on price or best place to get one from?..if it is the maf could it be something else ? as i read threads and some say if it runs the same when disconected that would be the problem, so what is it if it runs better when disconected ?

 

Also, if it runs perfectly OK without it.. what does it do, and is it needed ?

many thanks in advance, Ric.

It would be quicker for you to search the forum as this and simlar issues have been discussed many times before.

 

As a guide the MAF seems to make little difference to performance in petrol cars compared to diesels but it will have small effects on fuel/air ratios. If it runs better if disconnected it sounds faulty but there could be other reasons.

 

There are many cheap Chinese made MAFs masquerading as original parts on ebay - I bought one and it made things far worse.

 

I am not sure on your engines version but for mine you can buy the electronics part (from VW or GSF) of the MAF rather than the whole unit which saves a bit of money.

 

You could use VAG-COM of a simlar Ford compatible reader (not sure which one for your engine) and look at the MAF readings and see if they are within limits.

Hi,

I had the maf problem on my 2.0 N-reg last summer ( it took my a set of plugs and leads, two coil packs and a couple of thorough idle valve cleaning sessions before I found that it had been the MAF all along!!)

I ran the gal with the MAF disconnected for a couple of weeks before I bought one off ebay (I'm fairly sure that is where I bought it anyway - I'll try and check later) I don't remember it costing too much either. Remember to protect the female end of the MAF connector in a bit of cling film to protect the contacts from getting to much dirt in whilst you are between MAFs.
