I ran a test on my 2016 and found my long-term-fuel-trim is 10.16%. Truck has 130K miles and I recently changed the plenum gasket and spark plugs. After seeing this number I ran a test on my 2016 Sonata(51k miles) and long-term-fuel-trim was 0%. I was looking at the short-term-fuel-trim on a graph and did not see a nice graph oscillating between + and - values.
Is this 10.16% is normal for Frontier's?
If it's not what can I do to bring it close to 0%.
I get about 18mpg on highways and never got 23 mpg as advertised.
I bought the truck when it had 120k miles and I have used fuel injector cleaners every 5k miles.
Check-engine light was on recently and the error was fuel-system-lean and went away after changing the spark plugs and the plenum gasket which was really bad.
Right now the truck is running as expected without any issues.
