    2009 stx15f wont excelerate.

    Have a 2009 STX 15F that runs like the TPS is bad. Pull the throttle and just bogs down. You can get it to go if you work the throttle for a while. Had a parts ski in the shop, replaced the injectors and fuel pump as well. Complete Throttle body as well. Still runs like crap. I hate just changing parts, No Codes. Spark plugs look black and dry, like its to much fuel. Anybody have any ideas? Thanks. Ski has 100 hr on it.
