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?

Customer: replied 1 year ago.
Hi Eric, its 2007, check engine light is on all the time.
When i start the engine in the morning everything is perfect, the problem starts after few minutes driving, when the engine temperature is in between cold and warm (90 degrees).
And it jerks for about 2 minute (sometimes even engine stops) and thats it, after that everything is perfect again until next morning.
Any idea?

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

Ill be back with You.
