Hi.
I now have 2 new noises on my 99 Blazer.
One is a strange "buzzy" niose. It seems to happen more when the car is in drive. It reminds me of a noise one of my old cars had, which came from the speedometer cable. I don't drive the car that often, my wife drives it everyday, and she says she hears it once in a while when it's cold, and it goes away for a few days. I opened the hood last night, and found that the MAF wasn't connected where it should be connected at the air cleaner box, which must have happened when the guy changed the intake gaskets. I reconnected it, but didn't take a ride after, it was 11:00, and 20 degrees, and i was too tired to deal with it.
The other noise happens when I cut the wheels fast. I get this "rubbing", almost like a vibrating noise. Again, she seems to think it happens more when it's cold. I can't figure out where it's coming from, but it seems like I can feel it in the steering wheel.
Any ideas?
Thanks.

 

the buzzy noise could be the throttle cable touching the PCV valve

 

Thanks, I'll check that. It was probably moved when they did the intake gaskets.
