have 3.8L makes a ping noise when is cold
im trying to find out what that noise is all about when ever the car is cold when i just start the car like in the mornings is loses power the gear start shaking and looks like the car wants to turn off. Then i hear a knock on my right side by the front passanger tire. But when the car heat up is runs normal like 3 minutes later. I already changed spark plugs, EGR valve, Solenoid valve I was thinking it might be the MAF sensor by the air intake. I took it to auto zone for diagnostics and showed the the oxygen sensors code are bad, but i don't think the oxygen sensor will make that kind of noise in the car.
If you know any ideas what it could be please reply thanks:thumbsup
