I have cleaned the MAF and dont know what else to do. I sea foamed it maybe 8,000 miles ago so dont think that will have any effect. What else is left to try?

 

Get a real ranger.....like mine........ahhaha

 

1 Try a better brand of gas or gas with 89 octane.
2 Add a couple cans of dry-gas to the tank (Alcohol burns at a higher temp)
3 change the thermostat to 180 instead of 195 degree
4 Check the range of the TPS with a multimeter
5 change the O2 sensors.

 

Yes... Higher octane burns better...
