AllDarkCiv has a little shameless behaviour in the past
Re: Need help understanding self dianostics

Is there an actual problem or are you just trying to find one? I think that might be why no one has answered yet.

Re: Need help understanding self dianostics

seems your rpms are messed up. 545 is way too low, and 800 is a bit high but not too bad. does the engine shake with that low of rpm?
