I have 92 ls400 with about 236,xxx on the clock. I noticed my check engine light comes on when I don't warm the car up in the morning. When I start the car up in the morning i usually let it warm up for about 5-10 minutes til the temp gauge reads about 1/4 of the way up, no cel comes on when i drive after she is warmed up. When I don't warm up the car the cel comes on after being on the freeway for about 5 minutes. I also noticed the light comes on when accelerating... Sensors??
Thanks in advance
