Sorry if this has already been discussed, but I couldn’t find anything that pertained to my situation. So I have a 99 k2500 that I put a 383 vortec in. It is running incredibly badly. It shakes the whole truck at idle. I plugged a scanner into it and it is giving me “p0401 egr flow insufficient” “p1345 power train” “p0171 system too lean bank 1” “p0174 system too lean bank 2.” The egr code is because I blocked off both ends of the egr hose, my valve covers are too tall for it to fit. The lean bank 1 and 2 is because it has not been tuned yet I believe. The one that I believe is causing the shake and misfire is p1345 and ive been told it is due to timing. I have been messing around with the distributor for several days now and it has not helped at all. I’ve checked spark at cylinder 4 + 8, which was where the scanner said the misfire was. Both have good spark. I’m at a loss, any input would be helpful. Thank you in advance
