06 h3 truck started rough idle at slowing down to stop and sometimes would die. Engine light read misfire the first time light went off. Second time read both cam shaft sensors and crankshaft. Replaced both ran fine for a day than started again. Looked on here someone had same problem and a member ran him through all possible culprits. Pulled intake cover to find my Pcv crankshaft hose had come off filled coil pack and plug with oil. Replaced all that plus rest of plugs. Drove it traction light came on and engine light and went off. Truck ran fine again than started the rough idle again engine light back on with all these codes p0016, p0017,po068, p0106,po133,po171,po365,po366,po503. Can someone please tell me what the heck may be going on. Getting frustrating.

 

Well seeings how I just showed up to the dance....lol
I'm going to start from the beginning.
1> Check to see if you have replace oem battery connectors
2> Check to see when battery was last replaced...you may just want to replace it with the connectors
3> Check to see if you have dampness on passenger side front carpet, plastic area (if dampness, wet the bcm)
4> Check all grounds (i.e. take them off, remove them and clean them and surrounding area and reattach and coat with protective goop)

Start there!

Let us know..

 

Sorry I was out of town and had no signal. I just replaced the battery about 4 months ago. I did notice the negative battery was loose so I will replace the connectors to see if that helps. Some one else had mentioned that also and to check ground areas. I am not feeling any dampness in the passenger side. i will check all the above and update you.
