check engine light....on then off?
The check engine light has been coming on in my truck while under hard throttle. It is not at wot, but just rolling on the throttle, the check engine light will come on. By the time I get home, the light goes out. I put a code reader on my truck and it had no trouble or pending codes. Last night, I was merging onto a parkway, and I just rolled the throttle up to speed, and it came on for about 10 minutes. My EGTs were only at like 900. What could this be?
