Default speed control problem

I have a 2008 cc president that surges or jumps at half throttle. Full throttle it maxes out ok but anything less it acts like I'm pumping the accelerator! I'm thinking that it's a mcor problem any opinions out there?

I'm not on here much, but the few times I have had problems, a lot of guys read my post, but no one will comment! Is this the way new people are treated on this site? It's kind of hard to get to know people on here if no one will help me solve the ussues I have!!!

. . I don't think "new guys" are treated badly whatsoever . . actually, they get more attention than the seasoned members . . . it is a weekend and most people are busy with family, etc on weekends and answers sometimes take longer . . . you only posted your question about 30 hours ago and half of that time was "sleep time" . . . not everyone that reads posts feel qualified to provide answers . . . and yes, you may be dealing with an MCOR issue . . . emphasis on "may" . . .

One of the things some have done seems to tell if the wiper in the mcor is bad. They turn the key off and press the go pedal to the floor and back about 50 times or so. If that helps then you very likely have a bad mcor.

I jumped my blue to green wire on the mcor plug and it stopped my pedal problem. It took less than ten minutes. Can't say it will work for you but so far it has saved me $$$.
2011 president. It's only been 3 days now but no I'll effects yet .

My Precedent had the lazy pedal problem. I pushed it half way befor anything would happen. Then jumpy or if I pushed too fast maybe nothing would happen and sometimes it would surge? The fix was a new MCOR unit. It works as it should now.

P.S.
Sometimes people look at a thread hoping to find an answer to their own problems. So viewing stats don't necessarily reflect the number of techs reading & unwilling to help Please be patient

I would say a definite MCOR problem, a new one would probably solve your problem.

Thank you all for the input. I'm leaning toward the mcor also! I've been reading some old posts and found one that refered to a gcor or something like that! I'll go back and try to find it. The cart is a 48v cc president w/regent. I looked under it and never saw the mcor?
sorry I was so judgmental, and impatient!!!!

GCOR is for gas carts. I'm pretty sure the MCOR is under the "access hatch', which is under the floor mat
