Saturn Ion 07 50% power rough Idle Sign In

I have an 07 Saturn Ion and today the check engine light and a nother engine light with a down arrow came on and I lossed 50% of my power. After starting again, the car idled between 2,000 and 2,500RPM. Any ideas what it could be?

G- have the codes pulled at any of your local autoparts houses and have the codes pulled. Report back and we can help.

the second light you see is called a reduced power light it will illuminate for various reasons ,like he said have your codes checked and recorded ,usually it is mass air flow related problem if you temporarily unplug the maf while the key is off then restart and road test your car , if power seems ok now you probably require a maf sensor , i just encountered the same problem at work on an 05 but get it scanned asap sometimes just clearing the codes will reset the adaptive stradegy of the ecm and you will be good to go ..some food for thought hope it helps good luck ToddSly

by the way the mass air flow sensor is located in the duct work between the engine air filter and the throttle body in case you were wondering .........Todd
