Sluggish 8V92 - Jerry - 11-07-2012 07:43

I have a "1991 Bluebird Wanderlodge WB40" with a silver "8V92".

Lately it has become painfully slow at accelerating from a dead stop. It is
getting to the point of being unsafe to attempt to merge into traffic.

Once you get it rolling down the highway, it isn't so bad...I have no problems
maintaining 70mph.

Turbo boost will show a bit over 20 for a max, but when accelerating from a
stop, boost is less then 10, and the rpm's just don't want to rev up.

When it is first started, when cold, it does not sound as smooth as I thought it
used to.....almost like it has a slight mis. Seems to smooth out once it is
warm.

Bought it used with 160,000 miles, it now has a bit over 200,000 miles. The 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.

Has anyone else had this issue, or have any ideas at what I may need to check to
help resolve this problem?

Thanks, Jerry

Were primary and secondary fuel filters both replaced ? I'd take both of them out and see if they are dirty.



Thanks,

Markus

Without feeling it, it is hard to say. The 8V92 is an engine that has to rev
high before you get any torque going, so it is always slow off the line.

Just as described I would say that mine is the same, and is normal. That
includes turbo values. The only thing that is a question mark is your use of
"Lately" which implies that it didn't used to be that way.

Hi Jerry,

You mentioned the fuel filters have been recently serviced. Is that about the
time or shortly there after that your rough idle started? If it were me I would
start simply and economically by changing out the fuel filters again. Does your
Racor gauge show alot of restriction? Try that and see how you make out. At 200K
you are probably due for a valve adjustment and other tune up items.

Try the filters first. You may have one that is allowing a very slight amount of
air into the fuel system or an o ring not quite seated on your Racor.

Cheers
Gary

What temperature is cold? Mine does
not like temps much under 50 to start smoothly. I would also start with
the filters then to the valve adjustment. Had a valve adjustment done on
mine two years ago, lots of difference.

I would change out my RACOR filter first, Then if it is still sluggish check your air filter. Simple cheap things first

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.
