It could have a vacuum leak. check for vac leaks, especially to the brake booster line.

I changed the booster. I had someone tell me that was the problem, but it wasn't. then I had someone tell my the plugs had to be replaced so I replaced them. I had replaced the battery in the truck with a 650 cranking amp that's when it all stared had a 550 cranking amp in it. I asked if maybe could be the problem and they told me no wouldn't be the problem. So I don't know.
