Working on a 2019 JL (45,800 miles on it) and just changed the spark plugs/air filter and an oil change. Noticed one of the spark plugs was fouled up so I wound up checking the injectors (yup, two had corrosion on them - changed out the rail/injector assembly - we had a low-mile set laying around). Everything was good but the issue came back. Basically it's hard/extended cranking before it starts, once running STFT$% is at -2 and LTFT is at -16 (a bit much on the LTFT%). Reset fuel adaptives, also had cleaned the throttle body, ran an ETC relearn just for good measure. Still the same issue. No codes, No misfires...... Has anyone run across this issue yet? Yes, i'm an American tech working overseas....so manuals are a bit hard to come by.
