MAF questions pls...
 

How do you know or how can you tell when MAF needs replacement? Is there a way to tell or would you just notice this when the acceleration feels weird (not accelerating as before?) or what other problems will this give? Who's got the best MAF price and is this easy or hard to replace? Is this a Do it yourself kind of replacement or do you need to bring it in to a dealer?

Thanks in advance!

I suppose it depends on what model you have. Every post I have seen mentions trouble codes although the code is usually not specifically "MAF" but something else related.

do a search under `AMM`

depending on car model very easy to change yourself

chk out the prices above at FASTLANE

Sorry forgot to mention that. Have a W210 E55 running kleemann s/c and will soon be running S8. Does/will this make any difference on MAF problems?Thanks i'll check it out.
