Having problems with your 1992 Lexus Sc 300 ?
1995 Lexus SC300 looses power as temp increases.
\015 I have a 1995 Lexus SC300, and when cold, the car will start and run fine until it reaches normal operating temp. The higher the temp gets, the worse the car runs. At normal operating temp it will run, but has no power and develops a miss. Gently applying throttle will bring RPMs up, but slowly once warm. Quickly applying throttle once warm will cause it to miss, and bog, and sometimes die.126K miles on the car, and there are no error codes or service engine lights showing.I've replaced the ECU and MAF, as well as fuel filter and o2 sensors. Never anything except 93 octane fuel, and synthetic oil.I'm suspecting a temp sensor, or possibly bad/clogged cats.\015
Evil -mast I have the exact same problem, did you ever find a solution?
Could be clogged cats or may even be bad crank sensor.
