When starting the car while it is cold it idles rough (up and down) after warm up it idles fine. While driving it the motor boggs, pressing the gas pedal will not accelerate it. I can let it sit and idle and start driving again and it will be OK for 5-10 miles but then it does it again. It smokes bad when it does this from the tailpipe. I used jumper wire to self test and got codes by counting the check engine light in the dash. The codes that came up are: 122 throttle position circuit below minimum 157 MAF sensor voltage below minimum 172 Lack of HEGO switches indicates lean. Does this mean all of these items need replacing or is it that I am getting the christmas tree light affect? One affecting the other? Any help would be greatly appreciated. Thank you
have the same problem?
