Got a CEL monday morning it was a P1126, checked the MAF, looked clean, cleaned out the air filter and found it was rather dirty. Put it all back together and I am getting hesitation between 3.5k an 4k. Went out and decided to test the MAF with some info I found online. Upon testing the MAF I find the following, at idle I am getting 2.5v from pin 1 and 1.5v on pin 5. I pulled the sensor out and it is very clean, should it be dirty to need cleaning, or should I clean it anyhow. Could it be a fuel filter or something worse. Its a 01 S so I am not sure if its an external filter or not.
