Cylinders Hotter than other two.....

[Kevin]

I changed my spark plugs the other and noticed that cylinders 3 and 4 are hotter than 1 and 2. The plugs for 3 and 4 the electrode is like a deep red and the middle just below the porselen is all "blued" and discolered. The the other two look normal. I have an o2 sensor so it doesnt run lean. HELP!!! :lock:

most likely you have very heavy carbon build up in those cylinders.
you can try colder spark plugs.
go with 88-89 accord LXI plugs.
they are one step colder than 86-87 LXI plugs.
