My oil pressure sensor went out so I removed the intake and changed it. After putting everything back together I started the vehicle and now it Idles rough and I have a ticking noise coming from my engine. Also a new code p0307 it has a misfire in 7. I took it back apart and cleaned my injector it’s running rough. Any ideas what I could do next?

Hi,

Since you had it apart and not it's running rough, the first thing I would be checking for is an engine vacuum leak. It's possible a vacuum hose was left off or damaged.

Here is a link that shows how to find a leak:

Let me know what you find. Also, let me know if the misfire is gone or if there are any new codes.

Take care and God Bless,

Joe

So I have fixed the problem it ended up being a misfire on all 8 cylinders and my fuel injectors was still dirty, but now I’m just left with a tick that came from nowhere. Any ideas what that could be? I started driving it and the tick stops after I hit the speed limit but starts back up when I come to a stop again.

Hi,

If possible, record what you hear and upload it for me to hear. Hopefully, I'll be able to identify it.

I will watch for your reply.

Take care,
Joe

As you can hear from the video the tick stops once I get so far up on the RPMs then comes back as the RPMs goes back down.

I hear it. Do me a favor. Take a long-handled screwdriver or even a piece of 2x4 and place it on one valve cover at a time to see if you can tell which side it is coming from. I am thinking it is a loose rocker arm.

I know you replaced the oil pressure sensor. Was there ever a point the engine didn't have oil pressure?

Let me know.
