Check engine light was coming on then going away.ran fine.now stays on and starting to run rough on acceleration. gauges still read good.
If the light was flashing when it came on, then it means your engine is misfiring.
A solid light can mean anything from a loose/faulty gas cap to a transmission issue.
This
light comes on when the computer detects a
fault of some sort in its diagnostic tests. If it keeps detecting this
issue, the light will remain on. If the light turns off, then it has
detected that the issue may no longer be present.
In
order to find out what the exact reason was for your light, You need to
have your car computer scanned to retrieve the code that
the computer would have stored when the light triggered. Most garages
will do this free of charge. The code will tell you what may have
caused the light to initially turn on.
