check engine light came on while driving

[sf1964]

While driving to work this morning, my 2009 mazda cx-7 check engine light came on while accelerating onto the highway. The tachometer will not go above a 3 and I am not sure what the issue might be. I replaced all the plugs 2 months ago. She has 104,000 miles. Please help me!

Take it to Autozone and have them scan it. Then have them print the code so you can look it up when you get home. With that kind of mileage it could be a stuck EGR, shot 02, or a number of other issues.
