“Unstable Engine Performance and High LTFT1 Reading Issue”
As soon as I start the car, it begins to shake and alternates between stabilizing and shaking continuously. When I connected it to the OBD2 , I found that the Long Term Fuel Trim (LTFT1) percentage was higher than the others, as shown in the image. What’s the solution?- Alza

Starting & Running Very Rough
My 2008 Liberty (3.7L) suddenly began to run rough, like a timing or ignition issue might present. Now it won’t start at all, and sounds strange while cranking - popping noises, starts and barely runs, then stalls. Anyone had a similar experience with their KK Liberty? Thanks- [email protected]
