I have Lumina s (V6) 2005. Check powertrain sign came on. The computer scan give the following code (camshaft position sensor overadvanced...etc). Sometimes and when the car is cold and I start it, there is noise coming from the engine side (something stalling like (crrr crack..)). After that the car work but one time did not and I have to crank it again without any noise or problem. When the car is warm , there is no noise and the car starts normal. Please advise what could be the problem
