Remeber when you used to pour gas into carb throat to start an engine,
how it might 'cough'?

COULD also be sticky/leaky injector.  But the OTHER plugs in that bank
should be whiter than normal, as the system tries to lean out based on O2
sensor feedback.

START with warming the engine then disconnecting MAF connecter to see if
it runs better.  If so, clean or replace the MAF (clean should do it.)

Borrow a timing light to see if the coil is actually firing regularly.

Hi,

   My '95 Town Car with 4.6 SOHC V-8 is missing on the # 1 cylinder.  The
computer says so,  and the spark plug indicates incomplete combustion as it
is pretty black compared to all the others.  Sometimes it the engine
backfires into the intake plenum especially under acceleration.  I have
eliminated the coil pack (swapped sides), spark plug (replaced all) , and
spark plug wire (replaced) as the problem.  Should I be looking at fuel
delivery i.e. plugged injector, or even valve train problems or is there
something I have overlooked in the ignition sector?  My gut tells me it's
ignition related, especially because of the intermitent "cough" up the
intake manifold...reminds me of crossfire.  Is there an
electrical/electronic component that would only effect the # 1 cylinder that
I haven't already checked out, or should I move on to fuel or valve train?

   Thank you in advance anjyone who can help me.
