[QUOTE="aayjay, post: 1559625, member: 38197"] Hi you must have a California emissions lb7 like mine. I had the same issue and found a post that said it was the vacuum pump. Mine was actually making noise you could only hear standing in front of the truck. Replaced it and no issues since. Little bit of a pain to get to the three bolts but not too bad. Good Luck. Google lb7 vacuum pump. The site was yellow bullet something. [/QUOTE]
