Misfiring
I have a 2000 dodge neon with a 2.0 engine. I had
oil leak into the #4 spark plug tube which caused
bad misfiring. I cleaned the oil out, replaced the
tube seal and replaced the spark plugs. It still
misfires, turnes the new spark plugs black and if it
is put into gear, I have to put the brakes to the floor
to stop. Any ideas what to check for the continued
misfiring?
