My 2004 f150 with 85000 miles , was going down road with cruise control on 60 mpr check engine light came on started running rough when stopping all most cut off pulled codes says cylinder 1 and 2 misfire took to ford dealer they said plug n 1 broke and now wont hold compression when they ran test they say roller off or hole n piston truck runs with rough idle and can feel some like missing at higher speeds any info will be great

 

Hole in the piston huh? I doubt it. Possible, but not probable. Probably a bad coil pack or 2. Hole in a piston is pretty serious and would prolly cause more than a stutter or two. I could be wrong, and someone will tell me if I am, but seems far fetched to jump right to that conclusion-since it is the most expensive of the posibilities you have. Check your coil packs and plug wires.

 

find yourself a new dealership, seems to me that you found yourself a stealership

 

ya there saying that plug broke and got something n cylinder causing a hole n piston or rockers off causing no compression n #1 cylinder

 

I was thinking same thing took somewhere else today

 

ya man, my money says... coil pack... take to autozone they will diagnose for free! that will pinpoint which one/ones are are bad. coil packs are 40-60 bucks each. not too hard to replace yourself.

 

yeah hhaha just unplug the wire, pull out.. easy as cake loll

 

There was a hole n my piston so replacing engine with one that has 82000 miles
