96 F-250 chugs...please help

Hi all, I've got a 1996 F-250 4x4 with a fuel injected 460. When the truck is cold, it runs great. When it gets to operating temp, it will chug & stutter under a load (going uphill etc.) It does this whether or not the egr is hooked up. I replaced the temp. sending unit for the computer & that did nothing. Also, should this year truck have the OBD2 system in it or not? I can't find ANY port whatsoever to plug a reader of any kind into. Thanks in advance for your help.

You should pull the codes to look for any DTCs even if the Check Engine Light is not on.

There should be a 16 pin OBDII connecting point at the bottom of the dash, below the ashtray. It has a black cover and it is kind of tucked back out of sight.

This sounds like it is EGR related, but pull the codes and post them here.

if your truck was made in the later part of 95 then it may still have the OBD-I system and if so the plug for it will be under the hood on the drivers side in between the brake booster and the cruise control module. i have one like this state and ford call it a 96 but its actually a late 95.

Try to check the TP-Sensor.don't know fore shure but my 91' did the same.
