Check your fluid levels.
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle.
Theres bound to be changes but for the most part the only think it comes to mined Motor Mounts.
2.8/177ci v-6 or a 5.0/305 v-8 for the rs.
You can buy the check engine computer and the book comes with it. I know, I bought one. When your check engine light comes on, you plug it in and check the engine and it will give you the code and you look in the book for that code and it gives you the answer.
It's a 4L60E.
It is on because the ECU has detected a problem with the emissions system.
Some features which come on the new Chevy Z28 Camaro include the V8 engine, a track ready cooling system, and a rear spoiler. It also comes equipped with Pirelli racing tires.
why do check engine light comes on
The 86' Z28 comes stock with a 5.0 or 302 their both the same engine. a 1986 chevy camaro does not come with a 302 its a 305 a 302 is a ford motor not a che y motor know your facts i am a camaro fanatic i know these things about them plus i own a 1986 chevy camaro irocz z28 and its all original with the 305 4barrel carb thats how it should be btw mine has the t-tops in it
