300zxRB26 Posted April 29, 2006 Share Posted April 29, 2006 i did about 125 mph on the highway today then when i started to slow down every now and than it would chug a long for like a couple seconds....i need valve guide oil seals, think i fouled a plug?...the temp was also really high and i dont kno why...would the higher heat of the motor affect the plugs heat rating so it wold burn wrong?
