I've done sparkplugs+wires,fuel filter,K&N cleaning(Going to re-attach air box assembly) Any thing else? Check engine light is off, but Only getting 17.5 mpg's and top speed barely 120km/hr
I hear changing 02 sensor might help,
Cleaned maf sensor with maf cleaner, should I just buy new one? I just didn't want to spend $135 for a new one for nothing
Not sure what else I can do. Only at 110,000 kms, never loses a drop of oil. I want a tow a 14flt aluminum boat for summer tried towing on the highway top speed 104km/hr floored in 4th gear just slows down in OD. seems to run fine in the city just very low power on the highway very frustrating
Any advise on what else I can try ?

I believe I've found the problem

Noticed my crankshaft pulley wobbaly looks like it's about to fall out. They say it can screw up timing somehow,
