Ranger Posted July 30, 2011 Report Share Posted July 30, 2011 The CKP sensors don't always throw a code. If they are original, may as well change them anyway. You'll probably have to sooner or later. When was the TB last cleaned? Link to comment Share on other sites More sharing options...

BodybyFisher Posted July 30, 2011 Report Share Posted July 30, 2011 CKP sensor is the crank position sensor, it is what I was talking about above in my post. When they go bad, sometimes they do not set a code, but sometimes they do. Its always prudent to check for codes as I requested above to see what has been set. No doubt you will at least have a STALL code, but others may show up and help us. Follow the directions at the bottom of this post to retrieve the codes and post them here. TB is the throttle body, occasionally, the throttle body gets dirty, restricts air because the IAC or Idle Air Control is dirty or its port is clogged or dirty and it will stall as a result. The throttle body has a throat and a throttle plate and they must be cleaned especially the back and edges of the plate. The IAC should be removed and the pindle cleaned and the port cleaned. Do not flood the throttle body with carb or upper engine cleaner. Use a toothbrush, detail brush and rags with GM upper engine cleaner (UEC), the solvent not the spray foam. How mechanically inclined are you? Are you going to attempt this yourself?
