You need the Electrical Diagnostics Manual for the EFI System.....
Don't worry about TP sensor....
What get's people in trouble is that it is not to be touched.... That post was directed to Uncle Peeps anywho...
IAC failure can be masked as an Air Intake leak... Plain and simple...
That is the first sign to look for....

Thanks, Bob. I definitely agree about leaving the TPS alone. You may remember back with the old PCII's, you had to physically manipulate the TPS to set it. What a painful chore that was. IMHO, the PCII was definitely not Dynojet's finest hour.
And thanks for the endorsement of HP, Inc. I'm definitely attracted to that TB.
Oh, BTW, I'm fine with Marines.

I picked up a 01 road king over the winter with 17,000 miles on it. It is a 88 fuel ingection and is stock. The bike runs really well, but with myself and my wife, I'm consistly getting 33 mpg. Must less than my old 89 FXR. Is this in the normal range? I've checked the plugs and they are a little dark from fuel but not much. I've checked the brakes to make there wasn't any dragging. I've considered changing pipes, but I do admit this bike is quiet which I do appreciate after the FXR. Would one of the programmers help? Compression appears good, but I have not but a gauge on it yet. I just want to make sure I don't have anything potentially serious.

You can figure your mileage should continue to improve. Until recently, the most I could get, with a mix of superslab & local riding, was 36-38. My last tank gave me 40 mpg. I'm at around 2K miles. I think these puppies continue to break-in for the first few K miles. I'm running the V&H Ovals/Fuelpak/Stage-1 (no MoCo download).

Bob,
I have an "06" Street Glide, completely stock with 4,200 mi. I know it has the 8 deg. injectors, and I have not had any issues with cold starts, however, recently when I come to a stop when pulling in the clutch, the idle immediately drops below 1000 rpm to around 800, it used to more slowly return to around 1000 rpm and stay there. It is warmer now (air temperature) and I was wondering if this is temperature related or something with the IAC. I'm not one to cry wolf so I don't want to run to the dealer if it's normal. It also does't seem to idle as smoothly as it used to.
Thanks,
Mark

Here's my situation. 2001 RK with MM. Not sure if V&H pipes with chip make a difference, but in there. Have had problem for years, but it only raises its head when on road trip with others. In normal, around town driving I get the normal 40'ish mpg. When highway driving, I get close to 40 up to about 70 mph - when I increase to 75 mph, my mpg drops to around 23. Any insight would be appreciated, and I'm not a DIY'er when it comes to these type of issues.
