Auto- 1999 Chevy Suburban 2500 4x4 464 7.4 L
New purchase last week with 91,131 miles.
My service engine soon light just came on. As well, my gas gauge bounces all over the place, then always sits at 3/4 tank. Otherwise, runs great. What is the common reason.

Thank You, Tim

SES/CEL On

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.
