Hello, I have the car listed above that I'm working on and I need to know what size is the lug nut that came of the coil pack plate? It's two nuts and I lost them. I think I took a 13mm to get them off but to replace them what size is the thread? Not the bolts on the coil packs but the two lug nuts that hold the coil pack plate on.

Good morning,

They are 8 mm, 1.25 thread pitch.

You can get them at any parts store or hardware store.

No, I'm sorry. The lug nut thread size for the 13mm nut, and do you know the firing order for the spark plugs? Also the firing order for the coil packs? I'm trying to get the right order for the spark plug wires to connect to the coil packs. Guess I should of marked them, lol. But I was in a hurry.

The stud size is 8mm 1.25 by 1 1/2 inches.

I attached the wire location for the coils and the cylinder identification.

So I disconnected my fuel rail to fix somethings. How do I know if I have them connected correctly? It's not starting now like I may have them mixed up. What would be the danger if I have the fuel rail hoses crossed up and try to start?

So I took of the fuel lines, air box, MAP sensor, fuel injection system and cleaned up the engine. Tried to put it all back together some I marked some like the fuel lines I didn't now it started but running very rough and a few pieces of metal shot out the tail pipe red hot. Also I got a check engine code light on with this code.

Okay, the fuel lines are correct.

I do not like the metal out the tail pipe. I would do a compression test to see if something got into the engine and went out the back.

Do you have spark to the plugs?

I do yes, but maybe I mixed up the firing order along with the fuel line? Can you send me a diagram?

Okay. Well I appreciate the help, it's just annoying that I did all this work and the car isn't running properly. It was running just fine until I tool it apart, lol. But it must be something simple, maybe the firing order has it running rough. But why do you think those pieces came out the exhaust? It came out red hot and it's crated like it came from my catalytic converter.

That is why I suggested a compression test to be sure nothing got into the intake system.

You are welcome.

Hey Roy, so update: compression test fine it was my firing order that was right so I switched the spark plug wires and vroom! But I have a cylinder 6 misfire code if it isn't one thing its the next, lol. So I'm going to just buy one spark plug even though I just changed them all. They are all brand new but one spark wouldn't hurt to get the car running. Right?
