So from what I gather -ltft is Rich and +ltft is lean, I was on a 300 mile round trip tonight in my 01 gtp (dhp pcm, fwi) and I noticed my ltft's while cruising are around -14.8 to -15.1, at idle they are -18. So I'm running Rich right? What can I do to get these numbers back into an acceptable range? Car seems to run fine no kr, the car does have a bad vent/evap, no code but I have hard starts after a fill up. Thanks in advance guys.
