fuel pressure is constant at 62psi, static test and running thru rpm range. fuel volume is really good as well. what i cant understand is how it cleans up so suddenly and runs like a awesome beast until i start it the next time. what about a stuck EGR????? could it be dumping in exhaust gas during those fisrt 23-30 sec?
