!HELP NEEDED! GT Won't Idle!
Hey guys:
Got a question for you:
Every now and then, I encounter a problem where I try to start the car, but IF I can get it cranked over, it idles very rough, and dies out if I try to give it any throttle.
Fuel Pressure, Battery Voltage, and Oil Pressure are all OK according to my dash gauges.
Anyone else ever encountered this and have any ideas?
I'm thinking dead coil or spark plug?
Right now she's parked in front of my garage and I can't even keep her running long enough to pull her into the garage

you have a fuel pressure guage?, cause I'd say it sounds lika a fuel pump....Who knows though....I had an oxygen sensor go out on my focus and it did something very close to what you are experiancing....take it it and have it looked at....something is definatley wrong.

It's not throwing any trouble codes (won't even get to an RPM high enough that the CEL would come on), so there's nothing to read or clear w/ the SCT :hs:

Mustang operational 
Took out the MAF (looked super-clean
), put it back, re-flashed to stock, the car started, idled ****ty as hell for a minute then went back to normal...pulled the car back into the garage and re-flashed back to the 91 octane tune...**** started right up and idled fine 
Progressive revs to 4000RPM saw no issues or hiccups 
Going to have to call Brenspeed on Monday and talk to their tuner, and set up an appointment at Ford to have my O2 sensors, Coil Packs, and Fuel Pump/Filter looked at
