Bad MAP Sensor?

[werbicki]

My truck has been running great. Except for the non-working IC pump I haven't had any problems until about a week ago. Now, when I get in the truck and start it up, the stock boost gauge shows right at 0. I can hear the turbo spooling but nothing shows up (and I don't have a mechanical boost gauge - that's next!) When I drive it hesitates really bad. Then after about 10 minutes of driving the gauge kicks in and everything is great again! It is very consistent, like it needs time to warm up or something.

Is this the sign of a bad MAP sensor? I have a 2bar since everything on my setup is stock and I'm wondering if anyone has experienced this before?

Thanks,
Paul

Yeah it sounds like could be a bad map, any chance your vacuum lines are leaking and then sealing as it warms ups (ie have you replace your vacuum lines yet?)

No I haven't replaced them yet. It on my list

I would figure that if the lines were leaking that the guage would move a little bit. This thing is not moving at all until all of a sudden it kicks in and works fine.
