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.

Having trouble with engine killing or running rough even after it's warm.

not for sure but it could be your cam sensor. if the check engine light is on then take it to a parts store and they can run a scan and give you more information

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.

Chevy truck running rough 150,000 miles

Find out why the engine light is coming on, it is the info u probably need to fix the running rough problem. Most auto parts stores will read the codes stored in your trucks computer for free, write them down, and ask what they mean and how to correct the problem. If u need more info, return to this site w/ codes for further help.
