[DML] #1 cylinder update

[S E Ableman <s.ableman@xxxxxxxxxxxxxxxx>]

Dear List,

    In the past, I stated that #1 cylinder would carbon up so bad that 
it would no longer fire and raw gas would get into the crankcase. I had 
a chance to spend a few hours working on it. I did several things all in 
the same time frame. First I changed the oil & filter for the 3rd time 
in 50 miles. I wanted to make sure I didn't have gas in the oil. I also 
added RXP to the gas, an additive to remove carbon deposits. I also 
bought a new set of plug wires and replaced the one for # 1 cylinder, ( 
it was the only one with a problem ). Even thought I made several checks 
to test the wire, several of you suggested I replace it, and because of 
all the pulling , twisting and such that I did to it, there was some 
question as to its integrity. I also swapped the #1 injector with #2.  I 
drove the car for 30 minutes on the interstate at 65 MPH and in 4th 
gear. Then I returned home and checked the plugs, #1 has a nice white 
color to the porcelain, it has a light amount of carbon on the plug. A 
slight touch with my little finger takes it off. Prior to this test, the 
carbon was so bad that soot would ball up on the plug. All other plugs 
looked normal. I checked the dip stick and could not smell any gas 
present. I hope this is the fix, I'll know more after longer running. I 
think the problem was the plug wire all along. High voltage breakdown 
would be my guess. No amount of testing beats replacement.
    Thanks to all for your suggestions.

Steve
