Got A Miss ????????

[CinciCobra]

Hello everyone - new to the board... first time caller, long time listener......yeah whatever. I need some technical advice or brainstorming from smarter people than myself.

I have a '98 Cobra that is equipped w/ an ati procharger dcs-1 and the 3 core intercooler. I have had it for 10000 miles now and currently have 23000 on the car. I developed what feels like a miss last week, then the next morning I went out to trouble shoot it and it was gone. I drove it to work the next day and no problems through lunch. I got in it to go home and it reappeared. So I changed the plugs - it goes through em pretty damn quick, and it is a little better but still present. It has a backfire popping noise when revved, no power compared to the normal *** launching experience, and almost vibrates as 60 mph in fifth. As redneck and backwoods as it is, it also has a noticeable different exhaust beat out of the right pipe, kind of a blub blub blub as opposed to the grrrr that she always talks to me in. Christ it is late - I am sounding like an idiot here! Anyway, the left pipe sound totally normal. The fuel pressure is normal at 35 - 40 lbs w/ 30 lb injectors ( measure just before the fuel rails ). I am gonna pull the new plugs tommorrow and see what they tell me but I am thinking it may be a fried plug wire on the jacobs ignition. Any ideas friends? Thanks and sorry it is a little long.
