Cylinder layout 2007 tacoma

Can anyone tell me the # ofthe cylinders as the sit in the engine I have a random misfire on cylinder 6

 

if im not mistaken is goes like this:

5 - 6
3 - 4
1 - 2

if you look at it from the front cylinder 1 is on the passanger side and cylinder 6 is the one closest to the firewall on the driverside

someone correct me if im wrong...

 

Correct

 

Thank you that's what I thought I replaced the plug and coil and problem persists I have punched my converters out is it possible it's because of that and is there anyway to bypass the o2 sensors? Any ideas what to do next?

 

Is the electrical connector snug and clean on 6?

 

Yes snug and clean any chance of it being the o2's

 

I'm not sure maybe someone more qualified will chime in

 

when 1-5 misfire its usually fixable but when 6 misfires toyota says you need to do a full engine swap and they recommend the 5.7 V8 in its place...just so you know...

thanks i've been workin out

 

The above cylinder location is correct.

Unless the cat is totally clogged, it should not cause a misfire. Misfires can be a result of spark issues OR fuel issues, so remember that a dirty injector can cause a misfire as well. Also, a bad plug or ignition on the companion cylinder can actually show up a a miss on the coded cylinder. (meaning in this case that a bad spark plug or other ignition component on 3 can cause a code to set on 6) The firing order on these engines is 1,2,3,4,5,6. Strange to be in order, but it does happen. If you split the numbers in two and stack them, you will get the companion cylinders. Like this:
1 2 3
4 5 6

So 1 and 4, 2 and 5, 3 and 6.

These are a COP or coil-on-plug, so I would suggest moving the spark plug to Cylinder #2, and the coil to cylinder #4. Run the engine and see if the miss has moved. If it has, you will know based on what you moved to where. If the miss is still present, move the #3 coil to #5, and the #3 spark plug to #1. Retest. If the miss is STILL on 6, then you are looking at either a mechanical issue (Intake valve, exhaust valve, camshaft) or a fuel issue (Injector)
