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.
have the same problem?
