Purchased an 07 Jeep Liberty with 75,000 miles.
No codes or driveability issues.
Idle seems a little lopey to me as if lean and is more noticeable when the purge cycles.
Noticed the LT Fuel trims are over 9% on one bank and close to 9 on the other.
Any need for concern?
If so, how should I diag?
Thank you for any suggestions!
As Paul says in all of his videos, if your total trim is under 10, he doesn't worry about it at all. Action on your part would depend on the short term (STFT) number. If your STFT number is -9, you have no issue at all since your TFT number would be zero.
