I have read about a lot of people having this same issue on older posts but no one has posted the solution.
When my engine is warm and I shift into 2nd or 3rd gear, the motor bogs, shutters, shakes and shimmies until you hit 2k then takes off.
I have cleaned MAF, checked for air leaks, cleaned ICV, turned off my limited slip and will change fuel filter tomorrow.
Any one with this same problem find a fix?
I havent had the car for about a week, so I have no history.
I do know I need a thermostat because it runs cold. Any relation?
Also came with a NOPI muffler. Low Back pressure?
