Cylinder order on 4 cyl

[ixcocoyxi]

Hello all! I'm not new to forums but I'm trying to find out the cylinder numbers. I'm having a misfire on cyl 2 and usually the problem would be the fuel injector. I replaced the spark plugs and swapped the coil packs and the CEL stayed on cyl 2. I just need to know which one is 2. LOL!

I even looked on Google and all that was showing up were V6's.

Firing order is 1 3 4 2 on the 3RZ and 22R/RE, front to back.

They are just numbered in order front to back, so #1 is the very front, #4 is the very back. And most 4cyl engines fire 1,3,4,2 as was mentioned above.

Good luck finding the misfire, hope its something simple. I should be getting my 3RZ back from the machine shop after a complete rebuild. It started as a misfire on #1 that wouldn't go away, and after a leak-down and compression test I was amazed it still ran. #1 compressed at like 65psi and #4 only made 125psi, with the others in between someplace.

I hope that's not the case for you

Okay. I think I replaced the right one if it starts off 1 at the front. LOL! I'll keep you guys posted if the CEL reappears.

So I changed the fuel injector on the #2 (the second from the front) and the problem still exists. Going to do a compression test and see how that goes. Hopefully it's not bad.
