Hi my name is Allen!

When the check engine light is on this means there is a problem somewhere in the powertrain control system, which could be almost anything.

Here is what I need you to do, drive your vehicle to AutoZone or another auto parts store near you and have them pull the codes for you. Then get back to me and let me know what those codes are, and what the scanner say the code means.

We will move further with repair procedure after I know what the code or codes are.

Waiting for your reply!

SOURCE: Engine runs rough after about ten minutes /idles really low

Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

I'm pretty sure you would have service engine light on if you had vacuum leak! any how these cars are usually pretty good solid air hoses etc!if you have eng light OBD 2 scan for fault codes don't play the ge$$ing game!don't worry if you have idle problem that engine light will soon appear then scan if you do have air leak you will hear a whistle sound listen closely but keep in mind 10 switches can cause rough idle!air vent stuck open locate the intake park some times rodents make nests!!!seen it before or perhaps cable jumped off?linkage good places to start hope this helped
