Code P0108

[MMinWPB]

For the last few weeks, right after any really brisk acceleration, the check engine light comes on and it is always P0108...any advice on what may need to be cleaned/replaced?

109k miles, K&N CAI, new MSD coils, Lidio tune but it was also happening before I installed the tune...

Any thoughts would be appreciated.

I guess I am the only member that has ever thrown this code......

Thread probably just got overlooked.

This is a MAP code. Probably a bad sensor, but look here for a better description.

How recent did you put on the K&N?

Did the code started coming up after the K&N was installed?

Is the MAFS sensor plugged in?

When was the last time the MAFS was cleaned?

[MMinWPB]

K&N installed 5-6 months ago. Yes this code occurred only after the K&N was installed. MAF is plugged in (although I will double check the connection tonight). The MAF has not been cleaned in at least 21 months (as long as I've owned the car).

Put the stock intake on, clear the code and see if it comes back up. If it does, clean the MAF with some CRC QD Electronics Cleaner or CRC MAFS Cleaner, clear the code again and see if it comes back up again.

If it doesn't come back up after cleaning the MAFS then you should be good to put the K&N back on but if it does, you may need a new MAF. Make sure everything good and tight. A band clamp not tight will allow air to leak in and the MAF is reading the volume of air coming in.
