Sluggish 8V92

[Jerry]

Thanks for all the quick replies.

Have checked the filters and exhaust, they look okay. (Changed the final fuel
filter, cut the old one apart.) Recently changed the fuel/water separator,
gauge still shows it to be good. Plan on checking the fuel pressure today.

If I don't find anything obvious, I will have the valves and injectors looked
at.

I know these things don't jump off the line, but this thing is really getting
bad. There is just so little throttle response when accelerating from a dead
stop.

In response to how cold when doing cold starts....doesn't seem to matter if its
summer or winter.....here in Georgia, we're talking 60's down to 30's.

Thanks again, and if and when we find out the problem, I'll report back.

warm.

fuel and air filters have been recently serviced, but I have no knowledge of any
past maintenance history.....so I don't know if there are other issues that need
to be looked at....ie: valve settings, fuel injectors, etc.
