2007 Volvo S60 Question: MAF code after installing high-flow intake

Hello to all, I have a 2007 S60T5, on which I just installed a high-flow intake from Eurosport Tuning. I drove the car with no problem for 2 days, after which check engine light and MAF code 101 appeared. I re-checked and re-tightened all of the MAF connections and erased the code. Car was fine for about 100 miles and the code came on again. I erased the code again and car was fine for about another 100 miles after which the code returned. The car runs fine after the code re-appears, but this obviously has me concerned. Has anyone had similar issues with the installation of a free-flow intake? Might the ECU have to "re-learn" intake airflow with the new intake system? Thanks in advance for any suggestions / ideas. -

Do you happen to have a K&N air filter also - perhaps an other oil film type of filter installed? Zee -

Hello Zee, Thanks for your reply. While the filter is not a K&N, it is a similar type of filter. Based upon your question should I be concerned about possible oil contamination of the MAF? The filter does not appear to be "over-oiled" but your question leads me in that direction. Thanks in advance for any additional input! -

I'd try to clean the hot film element on the MAF sensor, since they are very sensitive of contamination, a slight oil film would work as an insulation. You can use a Qtip to wipe it carefully and you can see how dirty it was. CRC sells a very good cleaner dedicated to MAFs, you can buy it in most parts store. Zee -
