2009 Honda Civic LX 1.8L (R18A1). 294,000+ miles
I've noticed while scrolling through torque pro that my Short and long term fuel trims are the same and excessive at -71.88%. it throws a P0420 code and sometimes a P0302. I have recently replaced plugs and the P0302 hasn't come back. Odd issue on those, on cylinders 1 and 2, the plugs back out even though they're torqued to spec.
What should I look at?
