I think I found it this the hose coming off the back of the compressor going to the intake. Only bad part is I am sitting in a parking lot loaded with asphalt. So I hope it holds up till I get in 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74175-2004-ami370-popping-back-randomly/page/2/#findComment-552371 Share on other sites More sharing options...

No it didn’t I have hunted this problem but I finally found what it was today. The muffler had blown apart and the baffle had shot perfectly straight up was stuck In the exhaust tip. So the whistle noise that i thought was a turbo leak is were the exhaust was passing thru the little holes on the baffle. Not sure what was causing the poof noise but it sure sounded 100%!better after putting a new muffler on it. We will see how it does Tomorrow. 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74175-2004-ami370-popping-back-randomly/page/2/#findComment-552857 Share on other sites More sharing options...

The oddest stuff happens at times and when a guy is grasping at straws its always good to give just one more straw to grab for! It can be the simplest things! Make sure when getting an new muffler that they give you A muffler specked for a single stacked truck! The a dual stack muffler can also be restrictive When in installed on a single stack installation! All mufflers are not created Equal ! Don't ask me how I know!

I need one like that with a 44” body 4” inlet 5” outlet. The one I put on here last night has a flat plate in the middle of it. You can tell it can’t breathe very good.

Fred 🙂 Yeah I hate when people ask questions but they never post what fixed the problem. The muffler I put on it I don’t like it has a flat plate in the middle of it that the exhaust has to go around. I need to find something different. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74175-2004-ami370-popping-back-randomly/page/2/#findComment-552931 Share on other sites More sharing options...
