Intermittently has a hard time starting. But once its started it runs fine.

What is your question?

Did a scan and it said it was intermittent high voltage to the MAP sensor. Replaced sensor and still has the same problem. Took it back to get a scan again and same fault pops up. Was told it could be a leaky vacuum hose. When trying to start it sounds like it has a misfire. Sometimes it will be rough for a second or two after starting then go away. There is no problems once its running.
