Engine/Transmission (1998.5 - 2002) Got a heart beat?

[Alphacowboy]

I dont know if any of you have had this problem, but I think i FINALLY have this fixed. My truck has had a "heart beat" so to speak for over a year. I have tried everything from air filter, to a pusher pump, injector cleaner, and a few other things, and it never has gone completely away. Easy way to expain it, in the exhaust pipe, it would have what sounded like a heart beat. steady "bum, bum, bum" sound with ~2 secs or so between "beats" Well, while upgrading my fuel system to the Vulcan Big line system, I thought, Since I pulled the fuel filter housing to install fittings, might as well clean the MAP sensor. With the canister out of the way, its easy to get at. I pulled it (full of black crap) and cleaned it out with carb cleaner. Now, it idles smoother, and... NO HEART BEAT! Oo. I sure hope that is all it is. I was worried that maybe there was somthing wrong with the VP (replaced it just over a year ago) but I think that was the problem.

The beat goes on.

Hum. A Buddies truck has a "Beat" coming thru the BHAF. I heard mine do it once. It may be worth it clean the MAP and/or the IAT sensors, Right DPG?? Moose00
