Will not stay runningsounds like there is a heavy miss. New spark
plugs (NGK) and alternator. I pulled a spark plug and looked black and
smelled like fuel. I need to adjust the rocker arms because I hear a
tap from the valve cover. Any information would be helpfully.

All of the plugs look the same? The compression is good? You have looked
for vacuum leaks? You have checked the timing?

This is probably going to be a process of troubleshooting. First,
find out if it is an ignition problem.

You can buy a very cheap spark plug tester which will allow you to
evaluate the spark from each cable as the engine is running. That
will give you a point to work from.

If you find, for example, that one or two cables routinely misfire, look
at the individual cables (if they are not integrated into the cap), and at
the distributor cap. I have seen some similar cars that were prone
to get water, splash or condensation, inside the distributor. If that
happens you may burn a carbon trace inside the distributor cap and
you will have this type of problem.

In some cases, you can wash out the cap with WD-40 to get the water
out, and you may be able to restore ignition.

Let us know what you find.

I had an '85 doing the same thing. Check for vacuum or air leaks. Mine
came down to a crack in the intake hose, on the underside where the flutes
in the hose are.

New hose, $65. Duct Tape, $2.99...

How many miles/what condition? Tapping from under the valve cover? Drive
it till it drops.

They are fun cars to drive though, aren't they? I had an '85 GTS a few
years ago.

yes they all look the same, i have yet to obtain a compression gauge,
i didnt see any vacuum leaks upon visual inspection nor did i hear
anything but i will double check, timing i have not yet looked at,

it is possible the O2 sensor is out therefore causing the computer to
dump more fuel into the compression chamber therefore flooding the
system causing it to miss or not turn over?
