[corey.beggs]

So just as i was gettin happy about my egr delete/sct/edge insight bein on the way......my truck this mornin on the way to work while cruisin at 65 for about 15 mins decided it was gonna buck pretty hard so i turned the cruise off and push the pedal down did it again let off again then went back to normal i have no idea what it could be...truck runs fine and starts as easy as a gas motor. Anybody have any help for me please

If it's under 2000 rpm, my truck does the same under load and it's stock, it's lugging the motor because it doesn't have the torque under 2000 rpms.

it is under 2000 rpms but im under no load and also stock except for whats in my sig

This is not normal guys. I don't know what it is but its not normal. Probably some misfiring going on for some reason and you should check it out. Could have been as simple as an air bubble in the fuel line which is unlikely unless you recently changed fuel filters or something.

no havent changed them in 3500 miles now... would it have stored a code you think...i only ask cause when my egr cooler/oil cooler and gaskets just got replaced and no codes were stored i just noticed the signs also not even 400 miles ago i just had it in for a follow up i guess you could say and they said everything looks good. Thanks again

very possibly set a code, i would check it.

the only thing i have to check it with is a bully dog but its not on right now if i reinstall it to check will it erase it before i can read it?

No, it will promp you and ask if you want to clear codes.

Now if you tell it to tune the vehicle, that will clear codes, simply go straight to diagnosis and read codes, don't load any tunes.

alright ill try that but i think the bully dog auto installs the tunes when you install it, cause i dont think itll read without being installed but ill check
