Working with friends 06 Impala. There is a sweet smell coming from the vents at times when A/C is on. I know this usually indicates a faulty heater core, but I checked the floorboard carpet and felt no dampness this morning. Checked for visible leaks, and saw nothing. Didn't have a pressure tester available for more in depth check. Also when I pulled the pressure cap, it was gunked up with an orange gritty substance, which was really thick. I actually pulled a big ball of it out, so radiator definitely needs to be flushed. Even though I did not feel dampness I still believe the smell could be caused by a defective heater core which caused corroded fluid. Or corroded fluid caused defective core. Are there any other possibilities? The only thing that has me questioning is the lack of wetness on floor. Also tried to check for electrolysis with no indication. I am not sure of the accuracy of the cheap multi meter I was using either. Any ideas or suggestions or even a comformation of my heater core guess would be appreciated.

I have check engine light on & has a code P00011 & P0302 how do i fix this

it also shakes while in cruz control but not as much while using the gas petal

I changed the throttle bottle and drove around a few days and my dashboard light came on again saying engine power reduced. Is my fuel system failing

The evap solenoid on the engine has a rubber insulator.
The new one did not come with the rubber insulator but, has a grey plastic bottom.
Since the bottom is plastic, do I need the rubber insulator?
Thanks a lot.

Jiffy lube did an oil change on my 2006 Chevy impala police. And installed the wrong oil filter. Now my car is broke down. What can I do

06impala 3.5 Lt

I am currently replacing the entire oil filter adapter assembly and opted to replace the sensor as well. I noticed that the plug going to it just seems to look a bit off, the collar on it seems a little deep almost as though it had an o-ring. Is this accurate and perhaps this part fell off during removal?

Engine has a miss and a small knock , I ve replaced knock sensor did not help I was thinking about checking fuel pressure any suggestions

I can feel the cold but the blower comes on & off. Sometimes it just doesn't blow at all.
