EFI Sputtering at 40-50 mph

Hey All,

Thought I'd turn to the tech gurus here to see what you all thought. I've got an '04 FLHRSI (Road King Custom) with about 8600 miles. I've got the SE I upgrade, Bubs True Dual Headers and PCIII.

The bike has started to sputter when it is warmed up and I settle in at 40+ mph. When accelerating easily or even at WOT, the bike sometimes sputters and sometimes, doesn't. It pretty much seems to do it most when the just cruising...

The bike is still under warranty, but, I'm supposed to ride to Laughlin on Thursday and since the local dealers won't be open 'til Tuesday, I'm kind of cutting it short...

Any quick fix suggestions?

Thanks, in advance!

Ernie

Have you checked the FAQ section at the Dyno jet site?
I remember reading that a fraid wiring harness from the power commander can cause irratic running.
I would pull the side cover to see if your harness is rubbing against something and has now opened up.

Could have a wire or two shorting out.

Don't forget: your Power commander is shut down during your cold start.

It kicks in after the engine is fully warmed up.

Oh yeah, thanks for reminding me! I forgot to add that I tried it with the PC removed and the same thing happened...

Where did you get this info? I'm pretty sure the PC is on if the bike is on.

The PCII only came on after the engine was fully warmed. The PCIII is a different animal.

Thanks for the suggestions, guys! I tried checking the obvious stuff as well as I could and to no avail. I took your advice 04Glide and checked with San Diego HD. I am up in north county so I went the shorter distance... They seem optimistic that they can get it done by Weds...

I'll keep ya'll posted!

I had the same experience, turned out to be the fuel pump. Run great, sputter, Run great.

Thanks for posting up... Seems like it could be just about anything...

BTW, for anyone interested, it's almost 5:00pm and no call from the Dealership yet. I dropped it off yesterday at 4:00pm with two hours of business left.

They've had my bike for 24 hours now... I've called and left two messages to see if they have gotten a chance to look at it yet with no call back... One hour left of the service day...

I'm sure they are busy...

Well, I guess they were really busy today. I finally got through to them just before they closed and they didn't have a chance to get to it. They did say they'd get to it first thing tomorrow (Tues) morning, so we'll see...

UPDATE:

I called the dealership just after 1pm today. They hadn't even looked at my bike yet. The sales guy I bought my bike from was there on Sunday when I dropped it off and he told me to give him a call if it seemed to be dragging for some reason... Well, it was, so I gave him a call...

He called me back at about 2pm and told me that they were finally looking at it...

At 5:30pm, I called the service dept again, and they told me that they were able to create the problem but they were not able to figure out what was wrong with it yet...

They told me they would give me a call tomorrow (Weds) and keep me posted on their progress...

We'll see...
