You are in the Lincoln LS
What is this discussion about?
Lincoln LS, Sedan
May 07, 2009 (10:43 am)
Replaced all 6 spark plugs and the 3 'Bad' Coils, still runs the same with the same codes.
A compression test showed 120 on the cylinder that doesn't fire, and 130-140 on the two next to it. My method of checking may not have been the best though. I just pulled the plug and screwed the hose on, then started the car lol. Let it go for a few seconds and turned it off and red the results.
Anyone have a clue?

I am having a frustrating time with my car....ok, it intermittently goes into fail safe mode and I can only coast until I'm able to shut it totally off and it starts right back up. I was told it was coils 5 & 6, I replaced them by going to AZ and purchasing new plugs as well...this worked for a short while and started shutting off again. I noticed that when I press the accelerator slowly but continuously, the rpm needle does not go beyond 3...any ideas?

thank you for your response....I have not as of yet b/c I couldn't find a repair manual for my car with instructions on how to remove the intake valve...I was recently laid off and cannot afford to have the dealership put them in....I am thinking of taking it back for another diagnostic test to see if it is still reading the same coils.

Autozone, pep boys, etc. will usually read the code for free.

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.
