ORIGINAL: Apoc

do you guys think that my bucking situation (when driving a constant pace like 40 for instance and starts bucking) can be my fuel filter? or do you think it will be something else, hopefully cheap fix lol but give me any ideas what it could be.

OH and it only does it when im bout a quarter tank of gas? dont know if that has any significance but any help is apreciated Thanx

The clue is that it only does it when the fan is on.
The fan draws a decent amount of electricity and you might not have enough left to properly drive the fuel pump and ignition system.

What shape is your alternator/battery in these days?

Do you have a lot of electrical accessories and a powerful sound system?


I'd check the alternator and also check the fuel pressure when you have 1/4 tank of fuel.

mine did that when i first got it. I changed the tune to the 93 octane tune and put some fuel system cleaner and it went away. most likely was the injectors.
