Yes, this is definitely a possibility. There are about a half a dozen threads on here at the moment related to MAF issues, and it's pretty clear that there are MAF sensors being sold which simply don't do the job properly for these cars. Fortunately it has recently become much cheaper (c. £75) to buy the right, Bosch, one, thanks to some shrewd detective work by some guys here, who identified that the MAF sensor being sold for the BMW 5 series contained the same part as the Rover 75 one, just in a different housing and at a considerably lower cost. Search the recent threads with 'MAF' in the title to get more info.

Harry's right that this is not conclusive proof that the MAF is actually to blame. You could always test the output, by getting hold of an ODB2 reader such as this one, £7.98 on eBay - http://www.ebay.co.uk/itm/New-ELM327...item3cc0168b68 - and using it with Torque Pro on an Android smartphone. The figures it should be producing are given in this thread: http://www.the75andztclub.co.uk/foru...d.php?t=195871.
In your position, though, I'd be inclined to just buy the MAF sensor for £75 and if it doesn't solve your problem, sell it on here to someone, I'm sure someone would snap it up for a few quid under the going rate. |

You could try unplugging the maf and see if it improves ,you say you fitted a Bosch maf was it new or secondhand.

And is it, was it the correct MAF and a genuine (expensive) Bosch MAF from a reputable source? Unplugging it, it uses default settings, which should work fine. If it does, you have confirmed your MAF as the cause.

I think I have a similar problem. Except if I disconnect the MAF, the engine's twitching a lot on acceleration. Does anyone know what that might be? thank
