fessen Posted April 9, 2009 Share Posted April 9, 2009 My friends Supra has a case of overheating and misfiring. What would be the first things to check? And also what would be the worst case scenario for him. Link to comment Share on other sites More sharing options...
PORNSTARRACING Posted April 9, 2009 Share Posted April 9, 2009 when i got my supra it used to do that, cylinder 5 and 6 wernt firing, checked the coil pacs, they were fine, after 15 mins of driving the car would overheat badly, think one of the crank shafts snapped iirc was a long time ago Link to comment Share on other sites More sharing options...
AlexJames Posted April 9, 2009 Share Posted April 9, 2009 Misfiring.... spark plugs? ..... over heating, the seals in my rad cap were nackered so they stayed closed... that caused it to over heat too... Link to comment Share on other sites More sharing options...
