Hey guys, my mechanic did some tests on my engine for fun yesterday and noticed that my LTFT (Long term fuel trim) was high, around 17%.

I have a TRD CAI installed, I know my valve cover gaskets are leaking a little and will be replacing them shortly, I am curious if anyone has had this issue though and what the solution was in your case?

Additionally, my PCV valve is new and my vvt components are fine too (tested yesterday). I ran a compression test a year ago and everything was good, but maybe I didn't reconnect the vacuum lines properly or they could be a little damaged, who knows.

Thank you kindly!
