Until recently my BJ8 has run like a champ.  I now have a slight =
hesitation/miss on acceleration in all gears and when standing still.  I =
have cleaned the carbs (some black silt was in the bowls) and re-tuned =
the engine a couple of times as well as changed the plug wires and cap =
last night.  The engine ran like a top when I went to bed. =20

Not being one to leave good enough alone I decided to check and see if =
it was the distributor cap or the plugs that were the problem (I thought =
it had to be one of the two).  So this morning I put the old wires into =
the new cap, started it up and it ran rough.  I then tried the new wires =
in the old cap, started it up and it ran rough.  So I returned =
everything to how it was last night and now it runs rough with =
everything the same as last night.  Goblins must have gotten in there =
over the night, I guess.

Anyway, I=E2=80=99ve read the archives and tried most of the =
suggestions.  Today I removed the fuel filter, no difference although =
there was a bit of the black silt in the filter and the fuel looked =
cloudy (never had this before, it=E2=80=99s always been clear - byw, =
silt was in the carb bowls as well).  I looked at the distributer and =
plug wires in the dark, and there was some light at the location of plug =
No. 6.  When I put my finger behind the left exhaust pipe I got only =
very hot air.  When I placed my finger behind the right exhaust pipe I =
got a fluttering sound.  I=E2=80=99ve put in 2 new rotors, no change.  =20=

1. The coil is probably 15 years (10,000 miles) old.  I would test it =
but I don=E2=80=99t really know how.  Any suggestions on how to test the =
coil??? =20

2. I don=E2=80=99t want to jump to any conclusions, BUT, the miss =
started maybe 50 miles after filling up at a discount gas station (there =
was little choice).  Could the gas I put in be the culprit causing =
issues somewhere down line from the tank, i.e. clogging the fuel pumps =
(do they have internal filters - I don=E2=80=99t know)???  I=E2=80=99ve =
read about the lining of tanks dissolving and causing issues.  If the =
fuel I put in was high in ethanol, for example, could it dissolve the =
tank lining?  Is the residue from a dissolving tank lining a fine silt =
like product or something else?

I really appreciate any light you can throw on this and empathize with =
those that have preceded me with this kind of problem.  It is totally =
frustrating!!
