:I have been off the list for a while as my 87 has been moth balled
since
:last simmer, thank you in advance! I have had much assistance over the
:years! At the end of the summer last year after a 1200 mile trip my
engine
:started acting up. It starts well and warms up smoothly. As soon as it
:gets warm, simply at idle it starts running really rough as if it is
running
:on only 2 or 3 cylinders. Also black smoke from the exhaust. It I try
to
:drive, or rev the engine, it will accelerate very poorly, missing
terribly.
:I have been searching the archives to no avail. Can anyone offer an
idea at
:to what is going on?

I had similar symptoms last winter and suddenly very bad mileage.  I
naturally suspected the temp sensor, even changed it in freezing
weather, and then found that the ECU ground wire near the A/C mount had
broken at the connector.  A new connector and back to normal.
