Spark plug probs!!
I decided to change the plugs in my recently acquired 97 3.8 v6 t-bird
Motorcraft AWSF44PP, came out--and up to now havent been able to find
any in the UK!! I managed to cross ref them to a champion RS145LC, but
the originals only have half the thread of the champs, so when I try to
screw them in, they picking up loads of crud, and jamming up the threads.
Has anyone had the same problem--and how do I solve it??
