Been a long time since i posted, im posting for a friend that is having problems with his mustang. Here is what i can tell you about it. 2000, 4.6 supercharged. It has an SCT computer with tuner, trick flow heads, typhoon intake, 88lb. injectors, D1 procharger. The engine was just built in oklahoma city, dynoed, brought home, then he drove it a couple days and it developed a bad miss. Now it only misses after it warms up, then the engine temp starts climbing. Greatly appreciate any help on this. Thanks
