95 slight power problems

My pickup has recently has a lose of power and acceleration - nothing major but the throttle and fuel mileage has suffered. I replaced the fuel filter and air filter (K&N FIPK) recently, and a year ago installed 3-4" exhaust. No oil consumption, smoke or hard starting problems. Any help is appreciated.

Take the lid off the fuel filter cannister, drivers side of cannister about two inches down you will see an orifice or hole, in that hole is a screen that allows unused high pressure fuel to spill back into the low pressure side of the fuel pump. That screen can and will get dirty with (claims of some folks) bits and pieces of injector o-ring material. Same folks claim that cleaning this screen will indeed increase power, can help with fuel mileage issues etc etc......

You can do it two ways, one is to go through the lid of the cannister and use a Q-tip to remove the debris or the second (harder but more effective) way is to take the FPR off the side of the cannister. Remove the parts and pieces and clean the screen. Be cautioned to lay a rag in the valley to catch any parts that will (not might) fall down there.

how often do you change your fuel filter.......that could be the problem, also the fuel pump could be getting weak....you can check that with a manual fuel pressure gauge while driving (tape it to the wiper arm)......also, a MAP sensor that is malfunctioning can cause both those symptoms......without looking at it its tough to say because there are a multitude of reasons for reduced milage and power....but those are a few places to start......Marc
