Default Tech help please, running like chit

To make this as painless as possible...my idling has been an issue for a little over a month now and I know there is probably some tuning issues but I first turned to new plugs (NGK tr55), summit 8.5 wires, used MSD coils and nothing has helped. So I just called Charlie last Thursday to put me down for a retune and to call me when things calm down. I only drive my truck to work and back usually but since Brittney's car just got totaled we drove around a lot running errands it was fine until tonight when it had been sitting for a couple hours I start it up and the idle is extra choppy. Then we pull out of my neighborhood and thats when we knew something was wrong. The damn thing is louder and missing horribly, almost like a bad exhaust leak but no leak was found. While I was checking for leaks I noticed that it is running WAY rich also. What can this be, please don't tell me this is something thats going to be a PITA cause I've had enough this weekend...

sounds like a wire or plug is bad...maybe one of those msd coils. How do you know it was rich, smell?

I just am at a loss to what caused it to all of a sudden get worse in 3 hours of sitting and why did it get noticeably louder

Ok tonight I checked plugs and wires and nothing wrong (only 2 weeks old), and I figured I would have noticed if a coil was bad when I first installed them(2 weeks ago). But it really didn't act nearly this bad until yesterday.

So I went on another test drive and noticed at half throttle the oil pressure is pegged at 80 and its loud cause it sounds like the motor is trying hard but the power isn't there.. Could this be the shitty stall I'm about to replace(yank is in garage)? or the actual tranny? or motor problem? Please help, in need since Brit's car is wrecked...Thanks

Your sure your plugs are properly gapped and all the plugs are on good, especially on the coils. Not that i did that a month ago Have the capabilities to pull, or check for any codes.

I don't have any good ideas off the top of my head, but if you are in the area and need some help I could stare at it with you and hook up the HPT scanner to try and see what's going on. I'm sure your tune is locked, but I think I can still use the scanner.

Would yours be able to scan more things than the scan tool at Advance since my tune is locked? It would have to be this weekend at the earliest since I'm so swamped. If I can't come to a conclusion and you think it's worth your time I will give you a shout
