I just recently purchased this Z...It starts up great and runs very smoothly at all RPMS, and in all gears, up until 70-80mph. It doesn't matter if I am in 4th or 5th gear, when I hit 70-80mph it will start to stumble/hesitate slightly. If I slowly power through it, it is fine. If I try to accelerate quickly through it, it starts to really stumble...like it is running out of fuel. The ECU is not throwing any codes. I did read about the aftermarket intakes (I have a stillen) experiencing turbulence, but I don't understand the write up completely. It said there is supposed to be a shield somewhere, but mine is exposed all the way around. Has anyone had this problem? FYI I tried to search the forums for hours and could not find the same problem. If it's out there then let me know and I will continue looking. Thanks in advanced.
