Tips for cleaning MAF?

[Hrimfaxi]

There isn't a CEL, but I've come to the decision the MAF sensor could do with a clean - notably a lumpy idle when hot.

For example, I stopped earlier to pop in to pick something up at the shops, only parked for 5 or so minutes. Restarted the car and it began to idle lumpy, but all stopped as I began to pull away, was fine from then on.

It's a '02 Bugeye, if that helps.

I'm just after some tips from a trusted forum for giving it a clean up, as I don't fancy a £300 replacement for messing it up!

Cheers,

EDIT TO ADD - I've read through the performance filter thread, I'm running a K&N panel filter - I wonder if there's been some oil contamination from it being over-oiled? I'll be servicing my car soon, so opting for a Cosworth panel filter instead, just in case.

I usually use WD40 - Electrical contact cleaner on mine.

And it isn't the exposed electrodes i'm after, is it? It's the enclosed part?

I'm guessing it's best to just let it air dry?

Same as Nick, I use electrical contact cleaner and a clean microfibre. I did this job just yesterday and removed the K&N for a Cosworth dry filter. I have cleaned the sensor 3 times since running the K&N and every time it ends up coated in a dark, mucky film.

Thanks! That's confirmed my thoughts to bin the K&N..

Is it best to dis-connect the negative terminal on the battery when doing this?

Sorry for all the questions haha.

I simply unplugged the MAF and removed it.

As easy as that, thanks
