Engine cutting out at full throttle
Alright so I have a 03 Cobra with 46,000 miles. I have been having a lot of trouble with it lately from replacing the clutch, battery, alternator, exhaust leaks and now the engine cutting out at full throttle. I have a 02 sensor out, I dont know which one yet, but could this cause the car to not run right at full throttle? I cleared the code when it came on not thinking that I would need it to fix the sensor. What are some possibilities that could be wrong?
MGW short throw
Spec stage 2 clutch
K&N intake
2.8 pulley with idler
Diablo programmer
Accufab throttle body
BBK headers, longtubes
Bassani exhuast

my would cut out too under full throttle past 5000rpms. my problem though ended up being that their was water in the spark plug port on 2 of my plugs on the passenger head. my cop cover was crack, i dunno how, so im guessing that is how it got there. i just pull the coils out, cleaned everything and changed all my plugs will i was working in that area. problem solved. which one of your o2 sensors is out? you could just delete them with your diablo tuner if its the rear one.

well i just went out and programmed the front one out and changed the tune from a 91 octane pulley tune to just a pulley tune on the programmer. I cannot figure out y it would be set up for 91 since everyone always uses 93. but the car is screaming now so we see if this fixed the problem. Also be4 when the o2 sensor was out my gas milage dropped from 17 to 12 so this tank should tell me if the sensor is really out. thanks for your help if you have any more ideas let me kno.
