P0340 Code after Installing new Intake Cam (1 Viewer)

[trentcavanagh]

Hello,
First post!
Just got a 2005 Seq. and the previous owner replaced cam seals but removed the cams and neglected to place in the service bolt. Stupidly after removing the cam and placing it back in with service bolt (which I then removed) I neglected to hook up 3 of the coil packs on the passenger side which led to me ultimately snapping the cam. I replaced the cam and everything ran great for about 20 minutes until it started running very rough and threw a CEL. Ran the code and got a P0340. Now it is struggling to start and when it does, runs very rough. Replaced the cam position sensor with no improvement. Checked all wiring and everything seems to be within spec. All timing marks are aligned, triple checked that the cams were in correctly before putting on the intake cover and now I’m at a stand still. Not sure what to do next.

Any help would be appreciated! I’m really not sure what else to check.

Download the factory service manual and follow the step by step diagnostic flowchart contained therein to pinpoint the problem without wasting your time and money on “try this” parts cannon bull****.

Popped open the manifold and discovered my intake cam was snapped, I’m guessing I probably over-torqued them which caused it.

Never done anything like this so im learning as I go. Invested in a new torque wrench and discovered all bearing caps were way too tight. I’d imagine this fixes all the issues I’ve had.

you can't really get them too tight, youd be turning the threads out.
you aren't getting the cam installed properly before trying to torque it.

After looking at a service manual, I definitely was. I’m going to remove the passenger side and reinstall so nothing else gets broken.
