I have a 2003 Mazda Tribute and before this, had never heard of an ignition coil. I believe that that problem is they are becoming too hot and then become defective. When they do, my car acts like it has a transmission problem. I've had 3 replaced in the last 2 years (and I've only had the car since early 2010). The mechanic told me that because the car is a "Ford base" that this is just going to continue to happen. I was curious if anyone else's car has this problem, and if there is any possible way to slow or stop the damage to the coils. Thanks!
