Hi everyone !!!!
I am sure this has been through here more than once, but if anyone can help, i would be greatful. I have a 96 f-150, 5.0, auto. It has started to surge at a steady speed while driving. Seems fine while at idle and accelerating, just at the steady speed. Any suggestions???
96

 

I have this same problem, mine surges at around 25-45mph. highway speeds no problems, wot no problems, only when going at a steady speed, no codes. tps and o2 sensors were replaced recently also.

 

I also have a 96 F-150, and had the same problems. I suspected it would be the TPS or an oxygen sensor, something simple. But it turned out to be even simpler. My negative battery terminal was corroded pretty bad which cause an arc of electricity everyonce in a while. Chipped the corrosion off with a screw driver, put some marine grease on the terminal so it wouldn't happen again, and problem fixed ever since. Put some HEET or another product that gets rid of water in *both* of your tanks, water in your gas has a very similar effect.
