[QUOTE="Dan, post: 1040813, member: 74488"] Darn I've become one of those guys. Information requested. 2002 ST, 4.0, 2WD, Automatic, with 293,xxx miles. Installed a Jasper remanufactured engine less than 50k miles ago. This problem is getting worse, I believe it started a couple of weeks ago thought I might be imagining the slight hesitation. I believe the relevant codes are P0171 and P0174 (Fuel Trim too lean) Bank 1 and Bank 2. I took the ST for about a 60 mile drive today and had three occurrences seems to happen at idle like red lights etc. Like EddieS'04 commented I do believe the plethora of other codes are generated because of this I checked with the code reader and only captured the 71 and 74 codes. Appreciate any suggestions. [/QUOTE]
