Issue with Engine compression 2015 Winnebago Brave 26a

[Jus1084]

Hello all,

1st time posting and looking for some advice/help.

Recently on a trip from VT to MI one of the bolts on our manifold broke which created a good deal of noise. Also the check engine light came on which I attributed to the manifold, however got the bolt fixed and check engine remained.

The problem presents when traveling on any type of grade when the coach downshifts the RPMs climb but there is no power (on Michigan hills when usually climbing Vermont mountains with plenty of juice). Found myself cruising up hills at 45-55 mph with pedal all the way down to maintain speed.

Diagnostic testing showed misfire codes 300, 306, 316 which was initial addressed with new plug and coil on 6th cylinder. Issue still remains so a compression test was performed and showed low compression only on the 6th cylinder.

I have an appointment with a truck repair shop next week to dig in more and see what they can do since we had a cross country tripped planned the next few weeks.

Any advice, guidance, recommendations, or shared experience would be greatly appreciated. Stats below
