Spark Plug Question
Well my truck has started bucking AGAIN. I have a 2006 F150 Screw 4x4 with the 5.4L It has 94000 miles on it and this is gonna be the second time I have to change my plugs. Last time was at 64000. Same thing was happening before the first plug change. At speeds of 45 to 50 mph my truck starts to jerk during slow acceleration. So Im assuming its the plugs again. First plug change I put back the motorcraft plugs. Looking for a suggestion on what plugs I should replace them with. Should I go back with the motorcraft plugs or another brand? First plug change was a nightmare.......had to remove heads to get them out. Now I'm determined to do it myself with LOTS of patience.

-OR-
Champion 7989
New boots and dielectric....
IF the last set was installed correctly with hi-temp nickel anti-seize on the ground shield, this change should be cake.
I'd still run some Techron though ...
BTW - may not be plugs (this time).... *cough* COPS ( as in low-grade misfire - no CEL )
