Some trouble after timing job.
#11
Working on swapping plugs and coils over lunch. we'll see on the drive home if it follows. Might throw a new set of plugs, boots and springs at it this weekend. I have the autolite HT15 in now. Should I go with the motocrafts next, worth the $3 more a piece? Also looking at SMP brand boots. Don't know if there any good or not.

Me I use champion 7989 the only double platinum plug .Only because of the bad start ford got on mc plugs . Sp546 mc should be your ticket .These plugs hard to do and cause a lot of trouble no reason too scrimp on an important point .So say the astronauts on the booster seal .I used belden boots from napa..You want something trouble free for 60k.
