Ok, I need to get the year and engine size of your CX7
Is the check engine light on?
How does it idle when you first crank it up in the morning?
Possible causes are a faulty engine coolant temperature(ect) sensor, whose data is used to adjust fuel to air ratio when engine is cold, air intake or vacuum leak, or possible fuel leakdown in the fuel pump when setting for awhile.
We need the fault code stored in the computer which has tripped the check engine light. Unless you live in California, you can run it by any major parts store and they will do this for free. Once you get the code number, post it here and I can go from there
Ok, sounds good
