I have a 1997 Class C Ford motorhome with a V10....Last time we took it to the mountains it started surging under load (kinda like a miss but feels like surging) and it threw the CE light...Cleaned the MAF and replaced the fuel filter--MAF was trashed....Took it out this weekend and it's still doing the same thing under load but doesn't seem quite as bad (no CE light this time).

Any of you Ford guys experienced this?...Any help would be much appreciated.

Wouldn't that throw a misfire code?

Yes supposedly, it should tell which cylinder has a problem, when stating " kinda like a miss but feels like surging" is exactly the way mine felt when i took it in to the dealership, wound up being a coil pack, It could be an injector as well , but in either case it should set off the check engine light and kept a code,

Sadly there is no code, just checked for the fun of it when we got home...Hopefully a Ford dealer will look at this thing..Was hoping that maybe some other replaceable sensor was bad or something...Willing to try anything at this point, want to hold the dealer as a last option.

Check the fuel pressure. Just replaced a fuel pump on a 6.2L GM powered boat this weekend for the same issues. Replaced the fuel filter and anti siphon valve with no change so after $18 in parts we got to install a $508 fuel pump on the water in 92 deg heat in 2' seas. No fun at all. 2.5 hour job on that boat.

I recall reading that the coil packs are notorious for not throwing a code, or an incorrect one when going bad. Haven't experienced it first hand. Could be a vacuum leak too. You might want to go post on Ford Truck Enthusiasts for a much more focused response from a larger audience directly knowledgeable.

I've read somewhere that Ford MH's had a problem with water getting on the rear coil packs shorting them out.
There was also a problem with water getting into the intake and ruining the air filter. There was some kind of snorkel kit fix for that and some fabricated their own fix.

A GREAT RV resource, go to the forums- RV
There are people from through out the US and farther posting about their travels.

Thanks...It has a K&N cold air kit that doesn't seem to get wet...The coil packs are a possibility...It's going to the Ford dealer tomorrow night, somehow I think this is going to hurt...Most motorhomes end up with coach problems, this has been one mechanical thing after another--the Gulfstream coach has been flawless...It will be finding a new home after this season most likely if this doesn't stop....If I can't get the chassis that I want, we'll be buying a TT.

The coil packs are simple to replace, 5 minute job, its knowing which one needs replaced, the first one I shade replaced by the dealership because was under warranty, I replaced the next one myself about 2 years ago,
