Hi everybody
I have Lumina s (V6) 2005. Check powertrain sign came on. The computer scan give the following code“camshaft position sensor overadvanced...etc". 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.
