My Chevy SIlverado 1500 (2013) just had pistons changed. Immediately after I left the service, the engine light came on. Now the service is telling me there is P0300 error message on and they don't know why..... I am trying to figure out what could have een done wrong during pistons change. Or if they missed any cylinder damage when they were changing pistons....

 

Do you feel a misfire?

 

It probably has nothing to do with the pistons but is instead due to a connector to a sensor or controller that was not properly hooked up. Use a bright flash light and look under hood for anything that is not connected. You might also check for vacuum leaks in case the gasket material is leaking at the manifold.

S.D.

 

Why did you have to have pistons changed in a 2013? Warranty work??
