Help!

While cruising at any speed over 50 I notice a 'bogging' type sound. **It only happens when I let off the gas**. Sounds like bubbling water, etc. ALSO, my A/F goes LEAN. Like 17.0...to - - - read out. Not sure why. I changed the fuel filter, etc.

Not throwing any codes...what could this be?

you pro have too much air going in and not enough fire to burn off. check your plugs.

I will try to check them tomorrow.

 

[TheFranchise]

Anybody else have any ideas?

I will change the plugs probably next weekend.

That's normal.

Somebody got some new free flowing exhaust or cut out their cats, hence the sound, and normal for your A/F to go lean on decel... Stan

haha i love the sound of the exhaust popping on decel! It's all good brotha!

When I was running rich, mine would do that...floor it, then let off. A/F would go way up, and I'd sound like a harley davidson when they let off the gas, lol.....

I have been running this exhaust for a while...It has never done this before.

So everything is normal? I sure hope so...

Depends on what it sounds like it could be an exhaust leak, but slight popping is normal with free flowing exhaust.
