96 gmc stumble problem
 

Hi guys been trying to solve this problem i have with my truck for so long now, I do not know if I have asked anyone on this site for help yet so here it go's. I bought this 96 GMC ext 4x4 had a new tranny installed, just when I thought I could go and test this baby out the truck developed a stumble that I could not get rid of. I changed almost every small part I could change on the engine and then i went deeper, I changed the fuel injectors(new upgrade). maybe I should just tell you what I have done, cap,rotor,wires,plugs,coil, pickup coil,temp sensor,closed off egr,fuel filter has been changed o2s are done,has no cats on pipes. new 265s tires from 245s. stumble is like it's running out of gas,but I had a fuel pressure gauge on the truck when the truck was stumbling and the gauge showed 58 to 60 pounds of of pressure, what am I missing please help. ps no lights of any kind in dash or codes show up on reader.[:@]

that is suprising that its not showing any lights on the dash normally if the engine even acts up a little bit the light comes on. does it stumble and you have to let off the gas and step on it again or can you just hold the gas when it starts to stumble and it eventually picks back up

I can let off the gas and it will clear up for a bit, then come back.If I give it more gas it will quit to but always comes back.
