Jan 09, 2010 (11:56 am)
I had a misfire #6 spark plug, I replaced it.then # 5 had a misfire. I replaced all 6 cop's and spark plugs. still runs bad. the mechanic said it was the # 3 so he swithched the cop's and plugs around and it worked for a day...took it back and he said it was the cat. convertors. I replaced both passenger and drivers side and the FOUR 02 sensors upper and lower...he also replaced the fuel filter...now it shows a #2 misfire and he said he doesn't want to work on it any more and has done all he can do...any ideas?

Just to add another case hoping to attract more attention and find a solution: Here is my story
* I have an LS V8 Sport.
* First I get misfire on #7 and #8.
* When I remove sparks on #7, and #8 I see lots of oil.
* So i changed both valve cover gaskets with ford parts ($$$)
* I also replaced all sparkplugs. And the COP at #7 and #8.
* ....Then i get misfire on #5.
* I decide to change COP on #5 and #6 (just to complete all COP on that side of engine)
* ... Now I get misfire on #4 and #5!!!!!!!!!
Now I'm thinking the issue are not the COPs. Need some suggestions fast.
My card is riding VERY rough.
Thanks in advance!

What kind of spark plugs did you put in? I put double platnium in mine and it ran rough...I took it to a lincoln dealer and they replaced them with Iridium spark plugs. Use oem plugs and cop's or it will run rough and the misfire's will move around.

It will be costly to try, but
I'm willing to give it a shot.
I will update after I try it on the weekend.
