i got a 173 and a 137 tonight after a 40 mile trip farthest ive gone since head job I just put new injectors in

so its like I didn't put injectors in :/ anyway im out of thinkers like I beeped the harness back to the main harness all the injector + positives are continuous and all the - negatives beep back to the harness connector fine so the top harness is good I even have two pcms identicle one with less miles but both were giving me the 172 173 before ...I was all over the cam sensor before and im still not exactly sure I got the procedure right there may be developed slack and im not making a window Ive had others tell me the cam sensor is only important at start up but I question the behavior as not making a window and wondering if I got a bad component or two in the pcm

would like a list of the electronics to replace I would change the caps but I got a brain with less than 50k on it I want to think its a driver shorted like I could solder in one I think dam I had a pcm in my hand at the junk yard today but didn't buy it because it was for a non egr motor
