How does one tell if the MAP sensor is bad? What type of symtoms would a truck show if it is bad?

If you feel like answering, how bout the boost solenoid as well. What kind of problems would I see?? :dunno:

MAP would throw code 33 or 34

Dunno about the solenoid. Guess it would only boost 8 psi if it was messed up. :dunno:

Thanks guys. I think I'm good since I don't have any of the mentioned problems. I am really leaning towards replacing the CAT or probably the entire exaust. I think the CAT could be plugged. I checked my turbo and have no play but can't seem to get my boost past 10psi WOT.

Re: Bad MAP sensor???

you can borrow my boost solenoid if you would like. I had 15 P S I of boost the one day I drove my truck. let me know, I should be getting off work early today. Also if you need another exhaust you can borrow mine to verify that the cat is plugged, when you hit it does it rattle? All this will cost you is a ride in your truck :tup: .
