Any help I would appreciate. I have a 06 Fusion 600 HO. Bought it used this summer with around 2600 miles. Took it out tonight for the first time and it wasn't running clean. Has fresh gas, new plugs and the dealer said he went through it for me when i picked it up. It runs good and clean on idle. You take off and it has a little hesitation like normal then you get up to around 10 mph and it starts kinda gargling not running clean. You crack the throttle and it gargles and cleans up. Then you get back into it from 10mph to 30 mph and it has this problem. No problem beyond that, just in this range. Curious if this is the nature of these sleds or what is going on. Thanks for any info.
