It does seem to do it from the tailpipe when it happens. I changed the spark plug and put new gas in it and it seems to be doing better now. I accidentally put some of that E85 ethanol fuel (15%gasoline and 85% corn) in my toyhauler gas tank. Some $hiathead peeled the sticker off the pump and it looked like I was pumping 89 octane. I think that may have contributed to it even though i diluted it alot. I hope all of that fuel is gone from the tank. Guess I'll find out this week

Thanks for replying to my post :shocked2:

ya that could do it that new gas burns way clean like a lean burn so you could be leaned out to much just add a bottle of additive to the gas tank in the hauler and dont put it in anything else it ill start to folw plugs and ect... glad i could help out just let the brother know what happened caleb
