250 pro xs Won't take off ?

[linestretch]

I have just replaced all 6 coils after checking old ones and finding 2 that checked bad after heat testing. New coils, same problem. Then tried a buddy's coils and same problem. So here goes, It seems that after engine gets to temperature when the motor is started after fishing a while when you try to plane off it will start to go but has no power with the hot foot you can let off the gas and it may take 2 or 3 times before it will finally take off. Appears that pressing the gas slowly seems to help. Problem is intermittent and shows no fault code. I feel like its a tps problem but need some help. Forgot 2010 model

If you replaced all those coils and still have the same problem, I would think it's not the coils.
ECM, wire harness, or coil connectors.
Did you do a sweep test for the TPS?
The throttle problems could be the TPS.
Motor should have warranty, why are you tinkering with it?

You may also want to LOAD TEST your BATTERY. Remember- your battery needs a MINIMUM CAPACITY of 800 CCA or 1000 MCA at ANY TIME (even after you fish and run your pumps/graphs). That means you need MORE capacity than the "minimum".

If you need hands-on assistance.... we're in Greenville (SC).

We'll wait to hear back after he's run it a bit..... but it appears that he's had two separate problems (low oil level faults some time back causing Guardian), and (Starboard Overheat due to low water pressure- poppet valve sticking open and due for water pump).

Ran it pretty hard on the Dyno for him.... STRONG engine!

Replaced battery with AGM Diehard $ 200.00 Used this past weekend and problem still occured. Also still notice the hesitation on the take off. If you try to accellerate hard there is a slight pause when you hit the gas, It launches pauses and then takes off.

Let's get it in for some testing. Give me a holler when you have a minute, and we'll set something up.
