Well I did the seafoam, got really gas mileage and then it fell off and went back down. So I took the intake off and looked at the MAF sensor, it was black, the connectors were black and it looked ugly. So I unhooked it and since I didnt have maf cleaner at the moment I just took some water and cleaned what I could off and then took a soft cloth and cleaned the rest. It looks 100x better. However I was wondering if anyone has used the maf cleaner? Did it work for you? I did notice that my idle went up a little to like 800rpms were it was at 500rpms before.
