Hey everyone, recently my car has started to hesitate or buck upon acceleration and while driving normally. I experience these hesitations normally around 2500-3000 rpm. I've seen on the forum some people posting about a possible limp mode, but I still have all my power, just those hesitations.

An example is, if I drive at 45 mpg in 6th gear, low rpm I have no issues, If i drive 45 mph in 4th gear around 2.7k -3k rpm the will randomly feel like it's downshifting but rpm won't drop at all. It does it at all speeds, all gears so long as rpm is within the 2.5-3k range.

I've cleaned my filters on CAI and checked inside the intakes, cleaned MAF, cleaned throttle bodies, replaced spark plugs, reset my ECU and taken it to get tuned and everything showed up to be 100% fine. Had tuner drive with me and he felt the hesitation also but couldn't figure out what was causing it.

Anyone else have this issue, or resolve this issue?
