seafoam questions
alright, I finally ran seafoam to try and cure my spark knock problem....now, I changed the oil afterwards, then pulled the plugs out to see if they were bad but they seemed fine, only 40,000 miles on them and not really black from the seafoam treatment....so, should I replace the plugs anyway or should they be fine??

Sea foam in my experiance, assuming you ran it through the fuel tank has not caused any coaking on the plugs. As far as you spark knock problem, whaat grade gas are you using, and have you tried cleaning your MAF. i don't have the link handy for the proceedure for cleaning the maf. just another note i usually change my plugs at 30k and wires at 60k but i am just **** about those type of things

If the Seafoam was inhaled into the upper intake vis vis a vacuum line, and not dumped into the fuel tank, then the spark plugs could foul from all the carbon and coke being suddenly loosened up and burned in the combustion chambers. Even still, if the plugs look OK under inspection, then I'd leave them in.

Don't try re-gapping platinum or iridium plugs. If the gap is off, replace them. Use Autolite of Motorcraft plugs only. If you are using something else, they may be the problem, or contributing to the problem.
