The service engine soon light comes on and goes off intermitently only twice so far, the code produced at pepboys was p0104 which was the MAF sensor, so I have cleaned the MAF sensor which wasn, t very dirty to begin with. However, I still have the same issue. Can someone elaborate what the issue would be?

Also check if the throttle plate is fully closing-this will cause it to diesel/run-on
