Help Me Diagnose These Noises-
So I hadnt driven my car in a few days and I started and there was a slight squeal for maybe a second when I started the car. The same thing happened again today when I first started the car after not driving it for a day. Its about 30 degrees here in Denver today and the car definitely sounded a bit like a diesel. Any ideas?
The other issues I've noticed for the last week or so is that when I'm idling even when the engine is warm I sometimes get a sort of stutter. I checked for codes and I don't have any. What could this be?
I have accessport (last 500 miles), cone intake (last 500 miles), new plugs, fresh oil.
Thanks in advance for the help.
