Truck will only go about 20mph. My brother then installed a fuel filter as per auto zone. Nowproblem is wayyyy worse!!! Goes 20 then down to 5-10 mph with the RPM jumping all over the place. Ran better before filter was put in! Was told before when it was stalling out I needed a MAFS sensor ?? Could this be the problem? Obviously the filter wasn't bad? And a pain to get to I might add!!!! I'm a single girl and really need help as my brother is not a mechanic... Please ... ANY IDEAS WOULD BE APPRECIATED!!!!
