I asked about this 6 months ago but i wanted to see if anyone is having the problems now there cars are older. When i shift to every gear but 3rd it is perfect! But when i am speed shifting thru the gears and shift from 2nd to 3rd it does this stutter thing. It feels like im not getting enough fuel or something. It happens for a second then goes back to its job. It will feel like i let off the gas completely then stomp it again. But obviously im not doing that. Anyone have any ideas?? Right now with the motor mount, Fujita CAI, and the test pipe it does it. When i put the car back to stock for a month, still does it. It will do it every time. I have tried using 93 octane AND octane booster thinkin it was the gas does nothing. I cleaned the MAF sensor and it did nothing. I took it to the dealer and they have no clue. So im hurtin. Please give me ideas. Thanks everyone!
