When I first began posting about this 01 XLT I mentioned the previous owner had the truck detailed and the engined cleaned. After the cleaning the truck threw a code due to a COP getting water and had a rough idle. They were dried and the code cleared. I don't have a CEL but a rough idle on acceleration until the truck is at running temp. Now, this isn't a big problem but I believe one of those COPs may be damaged/going out since its a regular occurrence now. I don't want to cause further damage cause it is a bumpy ride. So...scale of 1-10 what's the difficulty to start swapping them out as I figure out which one(s) are the culprit? Thanks!

 

Not hard at all prob 2 mabey a 3 as long as someone didnt round the bolt off.just one bolt on each of them I think its a 7mm. But not positive I did it on my 00 when I had it. But you could wait a day or two and mabey a cel will come on

 

The big one is the one by the fuel pressure regulator. The back 2 can be a bear, but all in all, you should be able to remove one COP with not much difficulty. I would definitely check the codes and fix what is wrong. Better now, when it is one thing, than later when it could be a mulitiple.

 

I just changed out my plugs this weekend and while my motor is filthy as all hell and I had to do a lot of vacuuming and blowing out even used some good ole 40 to de gunk the holes before I pulled the plugs but without the nasty crap everywhere prolly would have taken me four hours the best thing to do is go one by one and pull the cop on the cylinder that missing first you have to check the spring in the boot and even take the rubber boot off I used carb cleaner and dried them and them sprayed wd-40 into them and put the on again u may think about replacing the plugs anyways since your there and don't be afraid to unhook things u need to to get a better working area good luck keep us updated
