Grand jeep Cherokee

Description:

I have had this jeep now for a year, I have just replaced the exhaust from the mid section to the back box. I have also just replaced the brakes and calipers around. The car has been used by myself everyday to and from my work. The engine management light has just started to come on and the jeep won't go above 3rd gear, it does go off and drives normal again.
