okay new issue 05 LR3 4.4 has been running great but went through car wash the other day and by the time I got out on the highway it started missing, i got back to the shop and showed #5 & 7 misfire so I pulled coils and plugs they looked fine not damp or anything. but replaced them just in case but still has the same miss. was it just a fluke with the car wash or is there another connector that can get wet and cause a problem.

 

What are the codes?

 

P0305, p0307, p0300,

 

well car wash was the cause, then I didn't look close at new plugs because they are non adjustable, evidently they had been dropped and electrodes where smashed shut. got new new ones and it was good to go.

 

Still odd you would have a problem with the car wash. Check your air filter and below the filter, in the bottom of the air box, should be a drain valve to let water drop out that has entered the air intake. Make sure that isn’t plugged up?
