Coil ignition pack
 

Okay so I found out today that it looks like I'm having to replace the coil ignition pack due to my ecu showing code p0354. From what I have read you only have to replace it on cylinder 1 (if you catch it early enough. But I can't figure out what cylinder is cylinder 1. I know it is on the passenger side. But is it front or back. Any advice would be appreciated

Cylinder 1 is the one that is most forward on the entire engine.

From a birds eye view

Front of car
------
2 1
4 3

Rear of car



Quoting this back from a 2012 thread for what it's worth:

Sweet that helps a lot. I appreciate it

Are you sure #1 coil is the bad actor ....... and not #4 .. ??

^ Yes 0351 is #1, 0352 is #2, 0353 is #3, 0354 is #4, at least according to the code reader I have which reads out some details.

Like many have mentioned, p0354 is coil pack D (or #4). The code is not to replace all of them, just the one that is having problems. You can reach that coil pack without moving or taking anything out of the engine, it should be a 15-30minutes max to change it (number 2 is the only real bitch, 1 and 3 are easy to change too).

So, @D86Ellis .... did you get your car fixed .. ??
