Thread: 98 4.6 issues

Hey guys I have a 98 f150 with the 4.6. I have changed the fuel filter and removed the cats and still I have this same problem. Seems when I press the petal to the floor it's bogging down like it's not getting gas to the engine and going up hills is becoming a huge problem without the trick wanting to shut down. Anyone know what may be my problem?

It was but it read o2 sensor I cleared it and it hasn't come back on yet. Motor idles fine untill about 3/4 throttle the misses almost and starts back only to mid again

Prolly been a while, just got it from my brother in law who got it at an auction. The plug wires are really long and one has a visible burn mark on it and I plan on replacingthem soon but I just don't see that killin the motor like it does under full throttle or hills. It's got a new knn air filter that's been washed other than that it's stock with some weak glass pack or something. Doubt any of that matter but I just want everything aftermarket known just in case

Anyone got any ideas? I'm thinkin about changing the fuel injectors cause it seems as though it's starving for fuel.
