Strange intake noise....
Wife and I went snowshoeing up in the hills today, taking advantage of some gorgeous winter weather we are having - albeit a bit nippy...-6 C
On our way home, we stopped at a gas bar for some fuel and some relief...and as we drove away, the truck was making a strange noise...reminded me of when we were kids and we would flip the air cleaner-cover to get some intake roar out of our pathetic little Datsun engines.
This continued all the way home. I usually hear this same sort of noise, from time to time when I drive away after a cold start, but it usually disappears after 5 or 10 minutes. Our fuel-stop was 45 minutes from our house...
Is this "normal" or is it something I should be concerned about? The truck ran fine otherwise.
