I just had the water pump and serpentine belt replaced on my cherokee around three days ago and everything was fine, now all of a sudden when I started driving the check engine light started flashing, and it seems to have lost some of it's get up and go. Please Help.

If the light is on, the computer has recognized a problem. Take it to a nationally recognized parts store and have them scan it for you. Most will do it for free, and it will point us in the right direction.

Let me know what you find. Also keep in mind, the mechanic may have bumped something or forgot to connect a sensor.
