Well FPR didn't fix problem . Im leaning towards # 5 injector . when its cold the balance rate is any wheres between + 4.0 to +5.8 at idle . then it warms up and goes back down to+ 2.3 to 1.9 + and then i cant get balance rates unless i put it in gear then its still + 3.5 or 5. all other balance rates are -1.2 to -2.2. a few are +2. something but they very so much . Im ordering one injector to see if that corrects the problem . when it missis its like i turn off the injector . And if that don't fix it I'm changing the FICM. I have seen you tube on that going bad and causing a miss . Have you changed your FICM yet ?
