FINALLY solved my rough idle+quick question>>
 

So since I bought my car about 2months ago it has had a rough idle. It would only happen about only 1/2 the time while sitting in neutral, the rpm's would bounce up and down between 800-850 rpms real quickly. So I finally had some spare time yesterday and changed changed all the spark plugs. The last plug I changed which was closest to the passanger seat< I guess that would be cylinder #4. Was almost completely bent, the top metal thing(dont know the name) was touching the electrode, I couldnt believe that cylinder was still firing. I have no idea how this could've happend. The gap had to have been .000000000001111125 Seriously. Now it is running smooth as butter and im happy.

I noticed when I was changing the plugs that my engine is a windsor?? I thought I heard somewhere that all 2000+ 4.6's were romeo's???

I think they started switching around there at the end of 2000.

RE: FINALLY solved my rough idle+quick question>>
 

yeah late 2000 for the start into 2001

RE: FINALLY solved my rough idle+quick question>>
 

So which one is better? romeo or windsor? Are there anyother changes other than where they are made?

didnt really say whos better

RE: FINALLY solved my rough idle+quick question>>
 

Yeah thats the same thing I thought. I have heard from people on this site that the windsor is stronger but this article kinda says that it cant stand nitrous and supercharging?

Cant wait to get the bumper Bransdaman78!:D Is it supposed to get to my place on monday or tuesday? I dont think that DSL tells you when the expected arrival date is.
