Does anyone know the firing order of the LSJ from left to right?

Just ran compression and from left to right the numbers are 150,180,180,180.

Now obviously I know there is a problem with the low cylinder reading, just need to find out what piston it is.

 

1 3 4 2

 

Must be a cracked ring land on #1.

Car still makes awesome power and pulls hard.

 

nitrous??

 

Everything is in. Solenoids aren't wired yet nor is the bottle filled so I never got to spray it.

I've had the suspicion for a while now, just never got to test it until today.

I just ran into trix's new block thread and everyone is saying his pistons that went are 1 and 4, both on the end which contradicts what the firing order listed above is.

 

I think you are confusing firing order with cylinder designation.

Firing order is as stated above: 1 3 4 2

Cylinder designation is 1 at the front of the engine (at the timing chain) and 4 at the rear of the engine.

 

Thank you

 

so if im following this properly - cylinder one is the one far left when your looking in the hood... I'm trying to figure out what wrong with my injector on cylinder 2. im getting a jerky feeling under power, but its not all the time, when it does it my check engine light comes on. after that it will go off....

 

Hey Kaiser I know it's four, almost five years later but did you ever find out what it was? I'm having the same problem.
