I have a 97 chevy 1500 and it acts like its running out of fuel/misfires/slips/stutters.... whatever you want to call it, between 40mph and 60mph other than that it runs great. I have replaced the fuel pump and assembly, fuel lines, fuel filter, fuel injectors, distributer cap and rotor, spark plugs and wires, upper and lower intake gaskets and it still does it. Any ideas of what it might be?

Its been scanned and its not throwing any codes

i'm guessing you attempted to pull any codes? after replacing all that stuff, i would suggest you find someone that has a scan tool.

i agree with mud but go to a reputable shop so the guy using the scan tool knows his business good luck

Welcome to the forum and howdy from TEXAS. Where abouts are you from my buddy has a Snap-On scanner that's what you need done to your truck don't use a cheap one it might cost more in the long run. Hey maybe go and talk to a Tech at a dealership and ask him if he will do it for $10.00-$20.00 dollars it will take him less than 10 minutes take a piece of paper & pen so that you can write down the codes or what it's going to say.
Good luck! GMC

Ditto to the code pulling..

It does sound like it could be the cam sensor though.

is it normal below 40 and above 60, did you check all vac hoses for leaks, are all wires plugged in to the distributor, if i remember right there is a tan wire with black stripe on fire wall make sure it is plugged in.
