So I finally figured out how to see the fault code. Looks like 0174. Where can I find what that is? I don't see a list in the owners manual.

I think I have them...from the service manual. Except I don't see 0174. I'll take a second look..maybe it got cut off.

[NMKawierider]

Nope...that's all of them. It's not listed. Re-check/count the flashes.

Just went out again. Blinks 10 times, short pause, blinks 1 time, short pause, blinks 7 times, short pause, blinks 4 times. Repeats cycle

P0174 is a standard lean condition code.

Lots of things can trigger it. I pulled this list from the internet.

Dirty or faulty mass airflow sensor (In this case - T-Map sensor)
Vacuum leaks
Weak fuel pump
Clogged or dirty fuel injectors
Clogged fuel filter
Exhaust leak
Faulty oxygen sensor
Faulty air-fuel ratio sensor

Thanks!  I'll give them a try.

I got into some water this last weekend.  The speedo started acting funny and my EFI lit up.  Now the speedo is back to working, and the EFI light is off when running.  When I turn the key and wait I'm getting 10 flashes, 5 flashes, 10 flashes, then 10 flashes.  So I'm assuming that is P0500? 

Anybody know where the speed sensor is?

The rotor for it is on the front output shaft/yoke and the sensor is mounted right there too. Take the center plastics off and you can see it.

This is the 500 and it's a little different but it's the same place on the 800s:

Just an FYI, my code just kind of went away.  The speedo started working again, and the code remained blinking.  Then it returned to normal.  Weird.  I didn't do anything, so I guess the sensor dried out.
