2004 225 HO #6 Intermitten Firing????

[Rude520]

Ok, you got to remember that #5 cylinder and #5 throttle body are on different sides.....IE: # 5 cylinder looking from the back of the engine is the bottom right......from the front of the engine the #5 throttle body is the bottom right.... The emm will correct idle to around 650 rpms.....even if you have a dead hole.....

You're shitting me???

I've never paid any attention to that. I'll be damned.

If that's the case then #6 throttle body is doing it. Hahaha. If I'm sitting in the seat looking at thel engine its bottom left that's pushing air out. Wow.

[mactlman]

bad reeds? blowing out throttle body?

[Rude520]

I didn't take it apart and look yet. But yes its blowing back out of throttle body. Other 5 will suck your hand into it. This one is pushing air back out.

[Bassmeister]

Sounds like a reed.....pull that throttle body and take a peek....

Is it #6 cylinder that has the clean plug???

Yessir

Now we're getting somewhere.....

[Rude520]

From what I can see with the throttle body removed I dont see any damage or chips or missing reeds. However it does appear to me, also comparing to the reed block beside it, that a few of the bottom reeds are not seating back closed at all. I believe Mike is right. We are getting somewhere.

Take a 9/64th Allen wrench and check the reed cage Allen head screws for tightness, they are on each side of each throttle body. I've seen the screws back off the cages a bit and not have a good seal. If they are all tight then it could be a bad reed cage gasket. You're going to have to take the TB's off and then pull the lower intake manifold and inspect. You'll need a new lower intake gasket at least.

[ChampioNman]

If you do pull the intake manifold off it would be a good time to install a set of Carson reeds.

[Rude520]

I may do that my friend.

[Bassmeister]

I second Champs motion....but you need to do them all at the same time.....then the whole intake needs to come off and new gaskets all around.

[Rude520]

Just wanted to update in case someone searches this. A new reed block gasket cured what ailed it. Ran it today and the idle is perfect and its back to running like a top!!! Thanks to everyone who had a hand in helping me fix this issue.
