Code PO373 & 374 Help
Ive spent two days now working on all suggestions that I could find through searches. I have replaced my battery, reseated all connections, checked sensors, etc. Before I remove my PCV and go back to stock I wanted to see if any one had recently had the same problem I am having.
2008 Street Bob. It has been running flawless even after the PCV instalation untill three days ago. It went dead on me going down the road and wouldn't fire back up untill a long wait. It then fired back up and went only a short distance and did the same. After making it back home and searching for help I found I had codes PO373 and 374. I cleared those and still have the same problem with no more codes coming up. It will crank without hesitation and run for only a short time and shut down. My next step is replacing crank sensor and go from there. I just wanted to get a fresh opinion on my problem if any one has had the same issue.
Thanks in advance for any help.

I know you said you reseated your connections already but thought i would share my experience anyways. I had water get in the main connector on my pcv when I washed the bike, ran like crap after it would get warm when I rode it. I think the ECM and/or pcv don't start working until the engine reaches a certain temp, 200 if my memory serves me right, which might explain why it works for a short distance before it acts up. I opened it up again and put dielectric grease on all the connectors and haven't had any problems at all since then. Hope this helps.
