I have a truck that is having some issues that seem to be electrical and wanted to see if anyone has ran into similar issues. The code that cannot be cleared is p0102. I've also gotten p0300 and a cam position code. I've watched the cam position on the scanner and it does not read anything. I've watched the 5v references since every code I'm getting comes out to be a 5v system when searching. Both 5v reference is at 0 on the scanner. I measure the voltage coming into the maf sensor and I'm reading 5v. I replaced the maf at first with no change. The engine starts missing once it reaches about 1500rpm and the engine power is reduced. The truck has fresh 40% over injectors and 10mm cp3 along with built transmission, PPEI tunes, airdog, s&b intake, wcfab egr delete with 3" bridge, 3" down pipe and straight exhaust.
