intermittent spn 0102 fmi 18 cm871 - jgriffin812 - Today
howdy yall, I have a 2009 Pete with a cm871 1.47 million miles. I am getting an intermittent low boost code, I have an aftermarket boost and pyro gauge that shows low boost, I haven't seen over 21psi since the code first showed up. When the code pops up my egts get very high 1200+ and my boost doesn't get over 17 to 18 usually lower. I can hear almost a screech from what sounds like the EGR. after a bit the screech will go away and then it builds up to 21 psi. My inline 6 box didn't want to connect to my truck the last time i tried it but my nexlink code reader has some live data if needed. any other info needed let me know and i will try to get it as soon as possible. thanks for your help.
