Okay my 96 supercab 7.3 4x4 5 speed with intake a fass fuel and ts and it's straight piped with only 189000 on fresh oil is seeming sluggish lately and when fully warm at idle the rpms slightly jump the truck kinda shakes a little please help realy worried about it thanks ahead a time

 

Anyone have any ideas

 

There's lots of ideas, how are the fuel filters? did ya get any trouble codes out of her. Surging sounds like she isn't getting the fuel or air is in the fuel, scan it for codes and let us know.

 

Okay I have code p0713 p1748 p0344 p0236 p0470 now I know a few are because of my zf5 swap but I don't think all are thanks ahead for replies

 

I don't have time to look up all your codes at the moment no do I have them memorized. Can you goggle them and post them back? We need more info.
