How do you know when the coil packs on a MKIV TT have gone bad? Everytime I put new plugs in they last @150-200 miles before the start to miss fire. I'm running NGK platinum plugs gapped at .032 and also tried 3330's but they both miss. My car gives me fair warning though, the check engine light comes on and the [!] light, after that the car will miss. My car is BPU++++ and is running extremely rich. I'm planning on getting a VPC and HKS ignition before tuning the car. I think the plugs are fouled so fast b/c it's running rich.... Anyone have a similar problems?

My car has 57k miles on it.
