I have a 95 5.0 that is having a couple issues right now. The first is that it is running rich like crazy( bout 10 mpg) and all i have is bolt-ons. The second is sometimes when im driving down the road it will just shut off on me, it has done this twice on me. Then i go to start it back up and it just turns over but doesnt start. If i sit there and let it cool down it will start right back up and then no issues.. The third is sometimes when i go to start it, it takes a while like it doesnt want to start, but then it starts.. But it hesitates.. What could be causing this? I had a msd blaster 2 coil on it but now a stock one could that be why it hesitates to start??? Should i go back to the msd?
