My 2002 Mercury 225 EFI at idle it runs rough.
1225433ZY

​

XXL SW​

Almost like there's water in the system(no water, clean/ new filters)
After it gets a little past idle it smooth's out and runs really good.

Compression is 150# all 6
Thanks,Jerry

Injector flooding or reed problem

 

[jerryjerry05]

Thanks.
Can you explain injector flooding?

Plugs good ?

Trash and deposits build up on pintle and injector doesn't seal when pressurized. It weeps causing cylinder to be excessive rich causing idle and troll problems.

Thanks again.
I kinda thought that's what it meant.
I'm fairly good with tools, could I clean the injectors myself?
Or do I need special tools?

The plugs are new.

I had twin 85's and replaced them with the 225.

I send all my customers injectors to Brucato. They clean,flow test and balance them so they all flow the same
