Matter of fact, the fuel filter was the very first thing I changed....It was the cheapest...
) The previous owner replaces the plugs, all in all about 6 months ago...what are the chances that 3 of the 4 intake side plugs are fouled? The number 3 plug fires all the time, however 1,2,4 dont spark at all...ever..and spark on 1,2,3,4 on the exhaust side is dropped at 4000rpm. This is definately a wierd problem...mind blowing....gives me a headache.
