Rough idling after Cam Tower Leak fix (1 Viewer)

[KRR]

Hi, all,
My LX is currently at the shop after getting the common cam tower leak and valley pan leak issue fixed. However, now the mechanics are trying sort out multiple misfire fault code that's happening. Already tried swapping out parts from one bank to the other with no luck.

The codes are as follows :
P0017 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor B)
P0300 Random Multiple Misfire
P0301/03/05/07 Misfire Detected (Misfiring on cylinder 1,3,5,7)

Is it electrical related or mechanical? Meaning the workshop did not time the engine properly after fixing the cam towers, and causing these codes?

Thank you all, hope to hear some feedback regarding this issue..

I am guessing plug wires are mixed up

The timing not done right is my first thought here. Are the errors on the same bank that work was done on?

Mixed up plug wire would be nice and easy...but would that trigger crank position sensor code?

Getting the cam tower leak fixed on both banks. Do you need special timing tools ? Or
can it also be adjusted manually?

It's matter of alligning chain right when crank and cams are in a right position. I beleive chains have marks. Modern engines are easy to time but need to follow the steps and make sure you are not off by a link/tooth.

Checking all wiring is definitely a good first step but I would imagine the shop knows that.

Hopefully popping cam cover off and checking timing is easy.

I also imagined the shop would know how to do it properly as well. Unfortunately, not so...

They're LC specialist, just very unfortunate that they're taking so long in getting things right.

Checking is easy, but getting it aligned consists of taking the cam covers off as well as the front part. It's labor intensive.
