Answer 1
Your exhaust turning red hot could be an indication of the engine receiving entirely too much fuel. This can be due to several reasons - the most common being an air leak / vacuum leak somewhere causing the engine to think it's running lean of fuel...which makes it ask for more fuel. You simply must have a diagnostic test performed. It may be too late for your catalytic converters anyway, if the problem has been ongoing for too long. -
Comment 1
the fuel injector could be bad too? or what other thing maybe cousing this problem becouse i all ready check for leaks and found nothing -
Comment 2
You could have an injector sticking open, no doubt. But this is not the most common cause. You would have a ton of fuel in the engine oil if this was the case. -
