so, ive been refreshing this TTA we picked up, now after 'fixing' this thing. she drives great, but then after a extended drive it only starts missing at interstate speeds, i replaced the coil pack and it cleaned it up a bit but she still misses under cruising speed after a few min of driving, down low and when under acceleration it was just fine. could the module be the issue, im mean ive literally been through the whole car, minus TPS, iac, maf and module. the car literally runs great, just after some time driving does it do this under light constant crusing speeds. thanks for the help in advance.
