This is for a friend, ok last night going to chicago to see some races he was going about 120 130 mph and all the sudden it sounded werd, we left the car on unpluged each spark plug wire and found cylinder 2 from left to right isnt doing anything. took the spark plug wire put it against the bolt on the head and their was spark, i just talk to him today and said he replaced the spark plug and still nuthin, he has a D15b7

 

might be low compression on that cylinder, or no fuel to it.

 

getting on a stock B7 like that is bound to screw something up after a while. I doubt it would be a clogged injector due to the speed you were going, but you could check anyway. The headgasket might have gotten messed up, so check your oil for coolant, and another possibility that comes to mind is shot piston rings in which case youd be burning oil.
