I too have just found out that my 02 f150 has a misfire in cylinder no.7 just came on here to find out what to do and find out which coil is no.7. now realizing that it is the 2nd from back on drivers side i am confused at how i can get it out and get it replaced. how easy is it to get at and replace? anybody know what size of fitting for the ratchet i will need?

Thanks Ali

 

I just replaced the plugs (motocraft 5.00 each) , boots(Autolite 2per box@8.00 each) and anti sieze and dielectric grease totaling $80.00. The coils were 35.00 for motocraft at Advanced Auto Parts.

P.S. thanks to all on here for your help to determine my misfire problems

 

I just did mine today on my 97 E-350. You have to remove the fuel rail out of the way. Hint , If you are going thru all of that, replace all plugs and bootson that side. Also use some dielectric grease on both ends of the boots and at the wire connections. Be sure to use some antiseize compound on the plug threads but not to close to the electrode part of the plug. My van runs like a top now with 113,000 mi. P.S. Replace all 8 if funds allow it. I was just going to do #8 but borrowed 35 bucks to finish and do it right the first time. GOOD LUCK to YA.

 

02 4.6L W. SCREW. Got a code on misfire cylinder 7. Got the plug and coil out and replaced, but can't seem to seat the #8 injector back into the fuel rail properly. Any work around or specific technique? I'm fairly sure that my o-rings are not pinched, just looking for an easy way to get the rail back on the dang injectors. Thanks in advance~!
