Well boy's im in need of some help again.My truck has been (running off) kinda stumbling when i am driving. Got a buzz test done and good news is all past the test. Did the cylinder contribution test and not good news. Cyliners 3,4,and 7 are not helping the motor run (failed the test). The truck has 360,ooo mi on her but does not burn oil and does not smoke out tail pipe. Any help? I hope it is not rings,could the injectors be bad but pass the buzz test?

Thank you

Which fuel filter screen are you reffering to? I've only changed my FF when it comes to fuel
How do you clean that screen wtih the fuel bowl in? Do you have to clean the fpr screen also?
Ahh ok so my '97 doesn't have one? How do I clean my '97s fpr screen?
wonderful thanks man!
Heck ya, that makes it super easy hehe
No problem
gauges gauges gauges. So much easier to address these questions with gauges.
Well I just cleaned my fpr and it was pretty gunky. It wasn't horrible, but it was certainly clogged with thick stuff. Thank for the advice!

Oh, and throttle response is DEFINITELY improved; especially at higher rpms. It's super responsive now.
Oh ya. I haven't driven it yet, so cant comment how it drives. I can just tell revving in neutral.
yes!!!! Sorry I should have updated this thread. Cleaning the fpr screen made NOTICEABLE difference in the starting, idling, reving, and driving characteristics of the truck. I think mileage went up a bit also.
Def worth a try. It takes all of 5mins, and the benefits of cleaning it are tremendous.
