It's real simple, Just unhook the negitave terminal on the battery for a minute or so and then hook it back up. This emptys the computer memory. The light should now be off, but it will probably come back on sooner or later. My 1999 Rodeo has had the CEL on for over a year. Could be gas cap, EGR valve being dirty, EGR tube being pluged, clean um with carb cleaner. If the truck also uses lots of oil, check the above EGR problems. Some say Isuzu used the CEL (check engine light) to get owners to bring their trucks in to get high dollar service done on otherwise undamaged trucks. You be the judge. This is not an uncommon problem.
