I bought a Ranger 4.0 recently and thought this car was great. I undertook a few projects found on the "how to forum"... WOW !!!
- Cleaned M.A.S
- Cleaned throttle body
- cleaned Air intake sensor
- Did throttle cable mod.
This made a huge differance and although none of the above were giving any problems , it improved power , mpg and shifting.... Highly reccomended. Thanx FRF
