5.4 engine surge
i have a 2000 f150 2wd bi fuel (natural gas and gasoline). It surges like it running out of gas, when you are at 1/4 throttle to 3/4 throttle. Tell you get the rpms up to about 2500. Then it runs great it will do this in every gear. It only does it when its running on natural gas, on gasoline it runs fine. Oh and some times if you turn it off, then start it up again it will run better or worse. I dont know if you have any expertece in natural gas trucks. But i thought i would ask to see if you had a idea. Thanks

Looking at the service disc on this kind of bi-fuel application scares me.
I'm glad I don't own one because the hardware is complicated and the number of places you could have a problem is overwhelming.
I can't even begin to offer any help.
Get to a dealer with it and pay the tab.
Most people here complain about just changing spark plugs let alone what you have to contend with.
Good luck.

The problem is geting a good tech to look at the problem and follow the troubleshooting path reccommended.
I don't think many have enough experience unless the dealer sends one tech to school on those systems.
Setting in front of a service adviser that has no real knowledge of the system and being told that, is not my idea of real effort.
The CNG section is seperate from the gas injection.
There are regulators, mixers and many different parts to the hardware.
I would reccomend you get a service disc for your year and study it good until you understand the operation then begin the trouble shooting.
Last I looked at this was for an owner in UK where they didn't even want to try so that guy was really stuck.
Keep looking for a dealer that will go about it in a reasonable way, right up front.
Anyone can throw parts at anything and have the luck of 1 in 100 of making a fix as long as the money keep flowing. They keep trying buy there way thu life as a substitute for knowledge..
