    2000 jeep Cherokee sport
    I have a 2000 jeep Cherokee sport 4.0 196,000 miles. This month started to update her a little. Put in new OEM fuel injectors and coil packs. Also put in a new programmed computer. Plugs, you name it. Then got a code for 02 sensors bank one sensor one, so replaced both . Now she runs worse until she is warm, but sometimes just dies. What should I check next..
