TPS not to Blame......

[Blueriversledz-Digger]

I have a 2012 Pro with 1800 km's and it started to produce a bog and hesitation if held around 6500-6700 rpm once in a while, running great at all other RPM ranges and hitting 8250 rpm on a pull. Was told it was the TPS senser causing this, not the case. After 2 weeks at the dealership and hours of testing sensers, connections, and injectors, they found the power valve nut inside the the valve body had loosened completely off. Not sure if this is a concern as of yet with the 2012's, but something to consider with all the bogging issues guys are having.

wow that a wierd one. Usually that nut is so tight you sometimes have to heat it to brake it loose.

Ya, we've had a few Head scratching issues with them this year.
