Sluggish 8V92

[Jerry]

Well...it appears the tech jumped the gun on the "bad injector" being the
problem. He installed the new injector and it still does not fire on that
cylinder. He actually is saying now that when under a load, it appears to be
missing on more then just the one cylinder.

Says he has to dig deeper to find out what's going on....this was a couple of
days ago, haven't heard anything new since then.

I'm beginning to think it may be the "DDEC II"...or something else along the
electronic end. Jerry
