So how do I know what I have?

I need to start somewhere? what is the list? 1 do this, 2 do that? if it isn't the check plugs, check wires like others have said, then what needs to get done?

the p0174 is the only code that is tripping as of now. it does have a miss.

you are right, I don't understand the situation, I need help to figure out what to do, and in what order.

I am really dreading that I blew my engine......

Jim,
I'm not going to argue any point but will tell you, that your attitude is showing and is the biggest issue you have at the moment.
If your a bit upset, it's because your upset at yourself for not being able to handle the problem. It's not the engine's fault.
You have the code, I described why the code set, go with it. A least I gave you some real and accurate help to begin.
Test compression on the cylinder you think is the cause of the misfire and see what it is.
Then make the decision on what next to do.
You have to follow through with each symptom and clear them until all is done unless a problem gets into a lot of work and or expense, then that becomes a decision.
This is no different than a good shop would do.
Good luck to you.

In order to do a compression check, you have to pull the spark plugs. When you pull them, examine them, if there's a miss one of the plugs will not look like the others. It may be damaged, it may be fouled, it may be burning white instead of brown. This is called plug reading.

Ok, so starting to work on it. All right/pass side plugs are out.

Left most plug is the front of the engine. Then so on.



They look all about equal.

Some look a little wet, but that is because I discoed the fuel rail for better access and it dripped gas all over the place.

Well, fml. I can't get the hose to thread in. The hose is too floppy and I can't drive the threads in straight so...

Also, is this relay that I pulled and flipped upside down the correct one to pull to disable the fuel pump so it can't start?

If you aren't sure, just trip the fuel inertia switch. Do you have an owner's manual? It has a relay and fuse chart. If you don't, just download it.

Yes, want to confirm. I pulled location 301 fuel pump relay which should be good. The one that is upside down in my pic

I did get a quote from a mobile mechanic, that said $100 for a compression check.

Honestly, doesn't sound that bad, especially if I am having issues.

I got the hose to loosen up a little with a heatgun, so will try and re-attempt it probably monday

Biting the bullet and having a mobile mechanic come and do the compression test tomorrow I don't feel like dealing with the left side fuel rail and all that goodness

Oh Man! I'm sorry that happened. What do you think caused it, running too lean, or too much timing advance from a tune?
