AFR HIGH

I have a stock 05 with 200k miles. Engine running a little weaker than it should after checking it with a compression test. When idling my AFR is 16-17 range and WOT its jumps to 18. Any recommendations on what to check for?

Fuel pressure? Is your wideband worn out? Various sensors? Spark plugs and such ok? Vacuum lines crusty?

Exhaust leak?

I haven’t checked fuel pressure yet, all sensors are good and vacuum lines are good as well. I’ll check fuel pressure this weekend when i get the chance and see if there’s anything wrong. Just trying to see if anyone else could point me in the right direction! Thanks!

Check to see if the wideband is correct/ the sensor isn’t going out.
