I keep getting code P0101 Mass or Volume Air Flow Circuit Range/Performance

I checked the MAF sensor and changed it with a new one. I Reset the code and the car started to run very strong.
The code came back after a day and the car started to runs a bet slow.
and some times the engine dies when coming to a stop.

My car is 2010 S240 with:

1-k&N filter
2-Headers with high flow cats
3-Quick Silver exhaust
4-Tune

Is there any thing I'm missing?? what do I need to look for?

Is it due to the K&N filter ?

Thank you for the help

Any help ??

So this happened on my Exige back when Sector111 owned it... Turned out to be the O-ring seal between the supercharger and the outlet elbow.

Check out their blog post on it for more info. Hope this helps!

edit: and incase it is the O-ring, you'll need part#: A128E6000F

Did you recently oil the filter?

You could remove the filter, or - better - get the paper filter and see how that goes.

Thank you very much for your help. I will work on it by next week.

Regarding the O-ring do you know if I can get it from Toyota parts? or from O-ring parts shop? as we don't have any lotus parts in our rubbish dealer.

Thank you again,

No, the filter is new and have not been oiled yet. Usually when I oil the K&N I let it set to dry for a day then reinstall it.

Thank you,

I'm not sure if you can get it from Toyota...

It may or may not be the O-ring in your case though. Read the blog post and follow the procedures they used to find the leak. It could be occurring at another part in the system.

 

[Hazim]

I agree with you. It could be loose bolts or a leak here or there.

I just want to be prepared for it.

Don't worry about it I'll take care of it.

I'm living with it

I put the stock unit on. And no more issue

 

[Hazim]

I should try to put the stock filter back and see what will happen.

Thanks for the advice.

Hazim any luck with this? My Ex-saudi Elise SC has the same error code pending, but I'm having massive hiccup / hesitation issues around 2,500 - 3,000 rpm. Car is running Cup Airbox with HKS Filter (Foam type not oiled), have cleaned MAF sensor (car has only done 1,700 km) but no luck - cleaning made it driveable again, but still something is very wrong :-S
