when im driving down the road almost every time at about 50 miles per hour my truck act like its running out of gas, like it is back firing. then i let off the gas and it runs good.im thinking gas filter , may be out of time , but im not verey good with this kind of thing only the basics. any info will be appreciated.

thanks :icon16:

More info would be nice.

yeah more info is really needed, but yes the fuel filter can cause that, same with low fuel pressure.
