Does anyone with a cobalt ss tc still have there stock intake and intercooler pipe?
|
Mine is still stock.
The SS/TC is one loud car while stock. It buzzes, ticks, and clicks at low speed. I noticed that when the trunk kicking sound occurs, the AFR gets bumped up to 14.7:1 like it is being purged or something. |

What about this one? When I park the car and shut off the engine about 30-40 seconds later I hear a loud click coming from the front of the car near the intercooler. It is maybe a little deeper of a sound than a click. I'll have to record it.
I have never heard the kicking in the trunk sound though. |

I have never heard the kicking in the trunk sound though. If you look at the Ecotec w/ DI used in the Equinox, it has a metric buttload of insulation on the engine. Imagine an average soccer mom driving a SS/TC - 100% of them will take the car in for weird noises coming from the engine. |
if you really did do searches & research before buying the car u should know what it is (the clicking i mean)...sticky right?!?!?!?;)

I have never heard the kicking in the trunk sound though. Very normal and necessary. |

What you are likely hearing is the throttle opening and closing. It's recalibrating itself. If you notice, the speedo and tach will flicker when it is doing this.

I believe there is a way to eliminate the clicking noise if it bugs you that much, I don't mind it on my 09 SS. I just say to my friends "Cobalts make all sorts of funky noises, they scream, click and woosh depending on the model". Good times

Oh... to add one.. That kicking noise you guys are talking about coming from the rear?
I think its the heat shield above the muffler expanding while its getting hot. It'll sound like someone is tapping on the back glass 3 times. The first time I heard that noise was a WTF moment. I turned around quickly expecting to see someone behind me. |

GM has a TSB out for this concern, its a cover that goes over the direct injection pump to isolate the noise.
This noise can be reduced by 50%, GM actually makes a part that will quiet this noise. Injector Pump Noise Reduction Cover GM Part # 12628069 The stock cover is a thin piece of black cardboard, while the new mod piece is much thicker; it looks like it is made of rubber or foam. This part costs less than $10. Thanks to Crate Engine Depot for this information. |
