I am having several problems and I'm not sure if they are connected.
When cold, the car wants to start hard. It Will crank and roll over, start to catch, then sputter out. Takes between 3-6 key turns for it to fire. Then, it will have no acceleration in first gear. I have to let it idle for about 5 minutes and then go back and forth in the driveway for it to start running normally. Then, suddenly, it will run like a champ. Until it gets warmer.
When the car has been running for about 30 minutes or so and I let it idle, it will start to sputter and choke out after about 3-5 minutes of sitting still. If I get the car moving before it stalls, it will drive fine again. If it stalls, it won't restart for about 20-30 minutes, after the engine has cooled down.
When cold, it throws the codes P0171 and P0174, system too lean. I have cleaned the MAP sensor, replaced all 6 spark plugs, and the O2 sensor in bank 2.
When hot enough to start stalling, the codes are P0700 and P0871 switch c circuit range, plus P0132. Everything I could find for the 871 code had to do with fluid pressure sensors, but when I went to look those parts up, I couldn't find them for my car.
At this point, I cannot afford a large repair bill or to get a different car. What would be the logical next step to take to try to repair this? I currently have a brand new fuel pump sitting in my living room, but want to avoid dropping the gas tank or rebuilding the transmission if I don't have to.
