Hey guys, unfortunately posting back in this thread as i have "the same" issue with hesitation between 2.5-3.5k rpms again, except this time cleaning throttle bodies has not worked. I also cleaned the maf sensors, air filters are clean, reset ecu, checked and "reset" brake switch, checked for intake leaks, using same 93oct fuel as always, oil temp is good and in operating temps when this happens, recently changed engine oil and its topped up and drove the car a few days before this and all was good. In other word, im frickin' stomped!
Rain has been pouring here in
PR the last few days but i havent taken the car out much, plus no flooding in my area.
Taking it tomorrow to the dealer to see whats going on.
