well once again ive got a missfire in cylinder 3. so i went to the zone and bought some new Motorcraft plugs. hopefully this will fix the problem.

 

I bet it does fix it.
I had the bosch plat 4's and recently changed them out for motorcraft platinums.The same here when i pulled them they were all white,not even a trace of tan color I knew something was up because it had a point in throttle when it felt like it was missing.My truck runs better than ever now with the motorcrafts

Which bosch plugs did you have?

 

not sure. i know they are bosch plats. but im not sure which ones. there are like 4 different kinds right?

 

not sure,i just bought the most expensive thinking they were best my truck did not like them at all!!!!

 

I hope yours don't look like this when yuh pull em out - if so , you' ll have to roll the truck over and shake to get ALL that Bosch shrapnel out of there

 

I have never seen anything like that. How many miles?

 

What kind of COP do you have? Hobart?

 

Hobart hahaha, NoNo , Those aren't mine, thankfully - some other dude on this site posted a few pics of what happened to his Bosch plugs, I kept this one - But yeah , that's something else ..

Honestly , I don't think the plug were the cause of this , but then again

 

well it seems to be running great now. it runs a lot stronger now

 

What did you do,switch plugs???

 

Looks like replacing Bosch plugs with Motorcrafts fixed it.

 

ya, i put some motorcraft ones in
