[QUOTE="justa03, post: 12221650, member: 32157"] Alright guys im getting a little bit lost on this one. Got my car back together and still have a hesitation. Did a PPRV delete thinking that it could be it. When ever I get into the throttle and it usually seems to be right around 3k the car kinda falls on its face and the shift flashes like its restarting. After doing some research found out the wire that gets tapped for the shiftlight is VPWR for the PCM. That wire is actually fed by the bigger wire right next to it at the same connector. The main power comes from the BJB and then goes through the CCRM into fuse F2.2 in the CJB. This might get a little bit confusing unless you have a good grasp on electronics. The wire that actually feeds VPWR to the tapped circuit for switched power for the shift light actually powers the coils. My question is could I have a bad coil that is back feeding power into this system causing the PCM to think it is being restarted VIA this and that the coil only acts up when under heavy load? I load tested the circuits and all of them pass, from there I ohmed out all the coils and all of them come out to be the same. Im thinking of taking the coils out of my dads GT500 and putting them in my car and going for a cruise and see if this cures anything. Just looking for anyones input or if anyone has heard of or had a similar concern like this. Thanks in advance for any info or advice. :beer: [/QUOTE]
