2. i checked my battery i bought it last week it has 12.5 volts but 0 CCA car starts as normal though
3. i used a Tech 2 scan tool and under the BCM i got code U1016 and U1096 as for the PCM i got code P0650
4. while i was using the scan tool it kept losing communication with the car as well as the reduce engine power goes off and on every 10 seconds or so

Don't know what you mean by "battery has 12.5 volts but 0 CCA" ???...I think 1016 and 1096 is loss of comm with PCM and BCM...if a ground or 12 volts shows up on the single wire Class 2 data line you will not be able to communicate with the car at all...you can start by checking the powers and grounds on the PCM and BCM.
