I took my car in to the shop and they found there was a lower intake manifold gasket leak. They replaced my upper and lower manifold gaskets and now it runs great! We have been going through a process of elimination and started with plugs and fuel filter, then battery, then cleaned the fuel injectors and finally the intake manifold gaskets. Replacing them seems to have done the trick.

I would take it back to the dealer and tell them the check engine light came on not long after oil change. Have them run the code on their dime...it's a reasonable request!

A loose gas cap will defintely trigger the engine light, but in most cases, it will reset itself within one week. Some cars don't have a reset which forces you to have a mechanic reset it for you.

SOURCE: 2005 mazda 3 2.3l that is burning oil (no leaks)

possibly the pcv but check if your cars exhaust smoke is blueish or white in color if it does and your car doesnt have an oil leak then sure its burning engine oil along with fuel, the piston rings is defective, since you replaced engine oil the additive that the owner has put with the oil to prevent blowby is gone thats why it starts burning oil.....

Sounds like your getting EGR at wrong time cause the valve is stuck open. Have them check the EGR valve out.

I have a 1989 5-series BMW which sometimes stalls after changing from reverse to drive. It also sometimes shakes when first driving in reverse before changing to drive.
