Answer 1

HI there,

This code is for to rich exhaust. Most often this is caused by an engine that is running to rich. This can be the result of something as simple as a dirty air filter, or one of the O2 sensors. Once in a while a leaking fuel injector will also cause the problem, but usually when that happens there is also a hard starting problem.
