1999 Chevy Lumina Check Engine Light

Unread post by Guest » Mon Dec 21, 2009 12:03 pm

The check engine light on my Chevy Lumina comes on. Sometimes it flashes, other times it is just on solid.
It seems to hesitate too when i push the gas hard.
What can cause the light and how do i turn it off.
I would like to repair it myself instead of taking it to a mcehanic.

A flashing check engine lihgt means that the engine is missfiring bad enough to cause catalytic converter damage.
The system needs to be scanned for codes.
This can be done for free at most of the large national parts store chains. It will find code P0300 missfires.
Spark plugs, plug wires, sticking injectors are all possibilities.
