Re: Jeep is sluggish, hesitates, pulsating?
Just wondering what you found out. My 06 Liberty is doing the same thing at approx 25-30 mph. Have had it to a couple mechanics, nobody can figure it out. One mechanic put in a chemical that cleans the fuel system and it helped for about a week. I got the code u1411 (implausible fuel delivery). It is only at slow speeds, when I am maintaining the speed. When I push on the accelerator, it sputters, shimmies, feels like it might be shifting, then takes off and goes great. One mechanic told me it was the tires. Ugh
