Robert,


Like they say, it could be anything..  but dumping the
codes will
give us a hint.

In a pinch I used a couple of wires, electrical tape
and a tail light
bulb.... so no excuses for not blinking out the codes
:)

how black is the tail pipe ?  how's your gas mileage ?

maybe one off the top of my head that you haven't done
yet...

- engine water temp sensor in back of passenger side
cyclinder head.

if it's flaky at all, you will usually run rich and
eventually trash the 
02 sensor....  this is a 25-35 dollar part...
