fori_2004 Posted August 10, 2012 Report Share Posted August 10, 2012 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. Link to comment Share on other sites More sharing options...
dany Posted August 12, 2012 Report Share Posted August 12, 2012 If noise was negligible and no loss in power when car is warmed, i would advise ignore it. As when engine starts it takes few seconds to lube all parts inside the engine at optimum temp of engine oil which is normal. Link to comment Share on other sites More sharing options...
