Well a couple weeks ago I replaced all plugs and one coil. Soon after that I had a misfire so I replaced the coil on number 7 and everything was fine, then after that about three days later 8 went out so changed that coil too. So I went surfing and on the way there about halfway I had another misfire on 6 so I kept goin and came back. All was about 150 miles. Got home and replaced it and it was fine again but noticed a bit of a loss in power. Now today 2 went out so I changed it and it was fine for a bit. While driving it sounds like its misfiring but no code yet. And while taking off it seems to hesitate to take off. It's sort of stuttering. I noticed a lot of liquid dripping from the cats but someone told me it could be a clogged cat. I did for a bit smell a foul smell but after the coil it went away.
Any help or ideas would be great
And thanks for reading this haha I'm stumped

 

When my cats clogged it was missing bad like ur explaining but the o2 sensor threw a code. If ur getting a code from ur cats and u are within 8years/80,000 miles on ur truck then they are under a warranty. If ur lucky Ford will replace the entire set up with both cats and resonatores free of charge. Good luck

 

Did it throw just the o2 code? Or was it saying the o2 an a cylinder?
And could this be a sign they're getting clogged?

 

Mine just threw a code last weekend and I went to advanced to read the code it said something about catalyst but the little wistle#?*! doing it said it wasnt a real code and everything was fine. Well, now when I have the air on and start accelerating it starts stinking in the cab and when I got out while it was running the exhaust smelled bad(not regular exhaust smell) and it felt way hotter than usual. Y'all think mine are going too?? That what I'm figuring, kind of hoping for it so I can cut the last two off.

 

Today now my truck says I have a random misfire and that both 2 and 5 are misfiring
And it's really sluggish
Is It possible to get my cats tested?

 

Check to make sure the huge vacuum line is plugged in on the very back of the upper intake. Its located up and almost center. You can see it standing on the passenger side of the truck.

 

Do u guys know if I remove the rear two cats would my truck still pass smog? The rear driver one is full of cat crumb inside lol it rattles alot.

 

It most likely won't, but never know
