Ok so for the last 2 weeks my car has been studdering really bad, it's not like a bogging out from the stock ecu it's not fuel cut its like popping at wot and sounds like not getting enough fuel, I have a 02 sensor heater circuit code for the sensor behind the cat, I took it out cleaned it and tested the heater circuit wires with a multimeter and there running 12 volts like they should, now I went and sprayed the injectors with brake cleaner wile car was running and it made the engine die down wich tells me there's a vac leak there I took off fuel rail and cleaned the groves the injectors go into, not the fuel rail but the engine side. It's the 2 left injectors if your facing the front of the car, the green ones. There were also no seals there either, there were O rings where the injectors go into the fuel rail but on the engine side there were no seals just those plastic ring things so I don't know if they are supposed to have seals or not. Also my car is running super rich, below 10.0 I installed the ssafc 3 days ago and no matter what map I put on it the car still runs pig rich, (I tried a few maps from the sticky) the ssafc is hooked up correct and I'm writing the maps to the ecu correct. Also today I just got a p0171 code bank 1 too lean wich I'm assuming is from the fuel injector leak.. My question is do you think the studdering is from the bank 2 o2 sensor or the injectors? It doesn't make sense because I'm still running super rich.. The O2 sensor on my exhaust mani is less then a month old too. That's what I'm running my A/f guage from. The MAF sensor is less then 2 months old and I changed and gapped the plugs correctly yesterday. Any ideas? All FMIC pips are good everything is good I checked it all so I'm stuck here what do you guys think?
