2000 Cherokee Sport 4.0 - I bought this reader because my engine is misfiring, probably the fuel vaporizing in fuel rail problem. Regardless I can only get the RPMs to read and nothing else. My check engine light is on and it says there are no codes being thrown out. I only have Torque lite but I can't find specific Chrysler/Jeep PID downloads.
Can someone point me in the right direction? What am I missing or is there a better app that reads the codes?

Thanks for the help in advance.

 

Fixed, seems to work great. Cleared the codes.
