The spark plugs were replaced at 140,000 km with NGK iridium plugs so I've been running these plugs for about 38,000 km. I usually do change the oil mostly before 5000 miles because I run walmart High mileage oil(I read in forums where people recommended to change walmart oil before 5000 miles).
Are there any other codes stored?
If so, what are they?
Inspect the connection and wiring at the #2 coil all the way to the larger bundle. I'm thinking maybe something along the way became sad when moved around for the spark plug change, then sadder over the next 38,000km.
After that, I'd do a compression test.

I don't see any other codes apart from P0302
I checked the ignition coil wiring for cylinder 2 using voltmeter I do see current b/w 8 - 14v, it'* consistent with other cylinders as well.
I got compression test kit from amazon, pulled the fuel pump fuse and tested the compression and I got approx 75 psi for most of the cylinders and I'm thinking that the compression test kit is wrong/broken.
