1999 Expedition

Hello all, I am new to the group and looking for some input. My 99 expedition started having an issue recently. When I start to pull a hill it will begin hesitating like it is trying to down shift. Once you give it plenty of throttle it will down shift. Once it does the service engine light starts flashing. It recently stayed on. I had the codes pulled and this is what I got.

#2 cylinder missfire. Doesn't seem like this would be the issue but you never know.

Rear speed sensor. I replaced this and the abs light had been on. Now it is off.

Cohesion Malfunction

Center Input Circuit Malfunction.

Anybody have any thoughts about the last two?

A misfire will definitely act like what you are describing.

Thanks for the input. That is definitely my next try. The other codes threw me off. I will give the missfire some work and see if it fixes the problem. Thanks again.
