We have been having problems with our 1998 gmc safari for the last 4 years. When ever it rains or snows the van misses and at times the van dies leaving me to call a tow truck. At times when the weather is bad it will not even run. We have replaced the cap and rotor, coil, and then it runs good for 2 months and it misses again really bad. We have taken it in to the dealer ship where we got it and they lied and said it was bad gas just to get us off their backs because they didnt know what was wrong. We have dumped so much money in this van we are at an end with the problem. can you help us decided what could be wrong or what needs to be checked?? we also have put it on a engine code scanner and all it says is miss fire. please help if you can thanks
