Go to Advance or Auto Zone and have them run an obd scan on it and it will pin point why your light is on and could solve your problem. This is often done for free.

Check engine light flashing in 2006 chevy hhr


If it is running rough & no check engine light on then the first thing I would to is tune it up. If you have a check engine light then pay someone to diagnosis it & go from there. Usually when the light comes on there is a more promenient issue; that is WHY the light continues to flash.

1999 chevy tahoe check guages light


it sounds like the speed sensor is faulty,but you should have it checked in case it is an output or input sensor too.whats happening is, since the computer has no eyes it totaly depends on sensors to know what is happening,if it sees no speed it won't up shift the transmission because it thinks your sitting still.

My 1998 chevy tahoe has trouble starting and it stalls out alot what do I do?


put a scanner on it and look at fuel trim/air flow, etc. If it's just running rough, look to correct that, new plugs/wires, vacuum leak, etc. The scanner will help tell you what the engine is looking for.
