Fuel Injection question

 Greetings All,

Barkeep set 'em up. Everyone have a drink on me.

I have a 2005 FLTRI that doesn't like to idle once it's warmed up.
Here's the particulars:

Idle is right about 1050 rpm once warmed up.
It will intermittently drop to about 400 rpm, sometimes will recover,
usually will die.
Runs fine once it's over about 1200 rpm.
If I hold the throttle at about 1200 rpm, it will run fine.

My thought was that it might be one particular cylinder that's causing
the issue. Here's the odd part. If I pull a plug wire, either plug
wire, doesn't matter which, idle drops to about 900 rpm and it doesn't
miss a beat. Put the plug wire back on, idle pops back up to about
1050 rpm and the stumble comes back.

I'm not sure where to go from here (other than to a real mechanic). It
acts like it's starved for fuel at idle. I thought maybe one of the
injectors was cutting out once it got warm but since pulling one plug
wire should have isolated one injector or the other didn't work, I'm
not sure.

Any suggestions are welcome.

Thanks,

Mark B

 
Goto a REAL mechanic!  a 1%'er Mechanic.

For the purposes of archiving an answer if anyone googles this later,
I found the problem. Turns out the connectors on the injectors were
swapped (no, I didn't do it. I just got the bike and it was like that
when I got it). Put them on the correct injectors and runs perfectly
now.
