Intermittent Go pedal

[JBanks23]

Hello everyone. New to the forum and seeking some help. I have a 2009 Club Car Precedent 48v cart. Batteries are less than 2 years old. I’ve had this issue intermittently since purchasing but lately it seems worse. When. I press the Go pedal I don’t get any response the first and sometimes second time til cart responds either forward or reverse. And lately (this issue recently started) when in reverse, the backup buzzer will cut out simultaneously when pressing pedal. So far I have replaced the F/R switch, solenoid, and did the conversion from TPS to MCOR (Thanks David) and none of these have remedied the problem. A little lost on where to go now to correct the issue. I’ve read lots of ideas on this forum and I think I’ve tried the ones that pertain to this issue unless I’ve missed something. Any ideas on what to do next are greatly appreciated.
