|pushrod||Are you getting any trouble codes - blinking FI light ? I had a PCIII and was having problems, was getting trouble code 8 ( eight flashes on the red FI light ) which was the code for TP sensor. On mine, The wire that connected the PCIII to the TP sensor wire was broken because of the vampire connector that was used on a lot of these. Soldered up the broken wire and it did good for a couple more years, then had other problems with the PCIII. Removed the PCIII and went back to the OEM setup in 2017 and have had no more issues. On the OEM setup the engine isn't quite as smooth at low speeds as it was with the PCIII but worth it not to have the headache. Replacing the FPR is a good idea and should be done. I did mine in 2013 just cost about $25 then and took about 40 minutes to change with basic tools. Tightening the battery terminals with a wrench, not a screw driver fixes a lot of issues. Doing the ground fix as mentioned here is also a must.|

Yes, change the FPR. It fails due to age, not mileage.
You can always take the PC3 off the bike and see how it runs. If the previous owner had it mapped, it was most likely made for max horsepower, so over rich. They have also failed before and as the PC3 was around in 2003, it may be very very old

|wildwise||Thanks, Merry Prankster! Don't know why but I've felt a little suspicious of the PCMIII since I really got to know my bike well. Even on the leanest PCMIII settings the bike still seems to run rich and I get crappy MPG.|

|wildwise||Hello again. Thanks to everyone here for all the great input and ideas! This is such a great forum with so many knowledgeable riders. What a great resource. As it turns out, I did the "ground fix" and put in some new plugs and it's running great. I just finished a nice long ride and it was perfect. I'm going to keep an eye on the other things mentioned here, too. The old plugs appear to have been a little carbon fouled. Should I change out the FPR anyway?|

Do yourself a favor today and now to test issues.
Not sure how your PCMIII is connected, but by pass it.
Disconnect it and connect OEM set up.
My Bike being an 02 had the cut out issue, ground fault in 03 riding back from CO VTX shindig.
I later added PCMIII, and it had issues, bike would run good but started acting all, ****ed.
Bypassed it, and bike ran like new. Removed all aspects of PCMIII still, but think I need to do plates.
Have rhinehardt flush cuts, with over 20k on em, either need to pack em or just love the POP/POP/THWAP.

|captvelcro||For me it was the PC3 having gone bad. FWIW I have one for sale if that's your issue.|

|wildwise||Thanks so much, Jim and everyone else! I'm digging in to it over the next few days and I'll post what I find!|

Regarding FPR: Possibly a record holder from 2014, VTXCRZR
I have a 2003 VTX 1800C with a little over 100,000 miles.
Back to cutting out---the PC3 and TPS tap as mentioned previously???

It is therefore possible that it already had been replaced by then, so no 'record'.
