Do you know part numbers for the MCOR 4 and a retailer? I'm reading that the "OEM103327901" has been discontinued on one site and another has it for $169. The MCOR 3 is the newest I can find.

It is my understanding that part number AM293001 gets you the MCOR and the cable adaptor.

Sorry I don't remember the part number but I got it from my local CC dealer. The package came with the new adapter cable and it seems to me that the cost was $125.00. They don't even stock the mocor 3 anymore just the mocor 4

True, but the MCOR4 will only fit Precedent models with the Gen2 pedal group. Make sure you guys know that.

I had a similar problem with my 2010 Precedent. It was running rough, with a jerky motion on the GO pedal. I decided to troubleshoot the MCOR with my digital volt meter and everything check out fine. Pulled the connecter plug off the MCOR and reconnected it. Put everything back together and went for a ride. The cart ran great. Problem solved (I thought). Couple weeks later same issue crop up. Pulled the connecting plug again on the MCOR and sprayed the plug and where it plugs into the MCOR with electrical contact cleaner. Made sure the plug was push in well and making a good connection. It has been over a month and have not had a problem since then. Cart has never ran better. Smooth acceleration and top end seems to be better. Coincidence, I don't think so. Definitely the plug was not getting good contact. Just saying.

Your issue is not the same as 99% of the rest of the people with MCOR failures.... You may be correct in your own situation, but myself, along with plenty of Club Car engineers have torn these things open and found the problem internally.

Looks like I got lucky on that one. Not often that I am in the 1% group.

Im still kinda new to this, how do you know if you have a Gen2 pedal Group? Also, what do you think of my original question. Replace now, or wait it out?

thanks,

thanks,
I'd have to see a picture of it to identify it. But, the gen 1 pedal group has a silver aluminum base to the brake pedal. On the gen2 it's got a piece of black plastic trim over it. It's also offset a bit. The accel pedal has a ridged texture to it on the Gen2. As far as replacement goes, I'd replace it simply because it would drive me crazy. It's just going to get worse. The throttle fluctuation is not going to leave you stranded though. An MCOR has two jobs. An internal microswitch tells the controller to engage the solenoid when you try to go. If this fails, it won't run. An internal rheostat (potentiometer) controls the throttle percentage. This is what's failing in your particular case. It's totally separate from the micro switch.
