2012 engine issues

2012 assault has really bad bottom end bog to it once its up in the rpms it cleans up. Check engine light comes on only when I bogs. It has 900 miles and is bone stock.

proper clutch weights for your altitude? Running good fuel on proper fuel setting? Have you cleaned your exhaust valves?

Sounds like moisture in your tps. Check with your dealer or disassemble and dry it out really well with a hair dryer and reassemble and get it to a dealer as soon as you can.

900 miles-- I would start with the exhaust valves. Can bog when the won't open at first and then they overcome stiction and motor will "clean up" after they open.

The engine light could be from deto caused by valves staying shut too long.

Change the fuel filter out yet ?

Adjust throttle cable? Mine had a half inch of slop
Some say it can cause the tps to be out of wack
