Recently purchased 2009 LGT 5EAT and I love it except for this stutter issue. For me it occurs when cruising around 2k rpm and slightly increasing throttle. It feels like the engine is bogging down like the transmission needs to down shift but doesn't. It will keep on stuttering as long as you keep the throttle constant, but if you apply a little more throttle it will downshift and the stutter will go away. I read through this entire thread and cannot figure out what is going on. I have no mods, but purchased a Cobb AP and tried OTS stage 1 map to try and fix the stutter. It did not fix it. I inspected the MAF and IAT and both are clean and shiny. Not sure what else to do and any advice would be appreciated.
