    Recently my engine has started to do some sort of spudder after I’ve pushed it a little on the freeway or give a punch with the a/c on. Acts as if there is a misfire... I’ve replaced the #3 spark plug several times. Engine has 208,000 miles on it. Any suggestions?

    Why have you changed #3 spark plug? Need more details.

    You're runnin with a distributor, no?
