    So when i changed my plugs a while ago they where a little on the whiter side like the motor was running lean. I figured it was normal since its an EFI truck (2.7l). It always kinda bothered me, but now i am noticing it more an is getting pregressively worse. When the truck is warmed up not so much as when its cold, if i punch the pedal or even just slightly aggressive with it the truck will kind of bubble and stumble before catching up and reving out. My truck is a manual tranny and this happens without letting the clutch out (not under load) but happens under load as well. I have no idea other than maybe a fuel problem? fuel pump? idk it only happens on the low range and around highway speeds my pick up is terrible!!! i have to be in 4th gear around 4000-5000 RPM for any kinde of "passing speed" on the highway.

    I dont know any ideas??

    Thanks
    Wolfgang

    Fuel filter stock? Seafoam, clean throttle body, maf sensor? All of those will make a big improvement on performance. If your concerned about it running lean you can do a fuel pressure check. If its a fuel problem check the fuel pressure first before you go out and buying parts. :thumbsup:

    Yea that is a good idea to replace them every so often, I need to replace mine and my fuel filter also. And Im not 100% sure on how to check the fuel pressure on these trucks, but google and youtube explain it well on other vehicles. :D
