lexuzzzzz Posted May 3, 2005 Share Posted May 3, 2005 whats up guys just bought my 93 sc400 a month ago, recently I have been experiencing slight chokes or hestation at around 20mph becoming more obviouse and obviouse. Last week freaked out when I saw my CAT smoking hot after a 2 hours driving at constant 80s Does anyone else also have this problem? what might have caused this? coil? sensers? I like to start by checking out the plugsmyself but have no knowledge of the car.. How do I get to it, and if I need to change it, what is recommended?
