Had the new to me viper out today for the first time. Didn’t run to bad, needs some clutch work as it only get up to 8200 rpms. Main issue is the sled will stall randomly when riding under 4500 rpms. When coming to an intersection it will stall and die sometimes. When riding in town or in slow are where it’s running under 4500 it will stall every now and then. It doesn’t always die but stalls the. Surges back. It’s a 14 xtx with mpi turbo. Looking for suggestions. I’ve checks the tps and it’s 0% at no throttle and 99% at wide open. Noticed on the A/F gage when it stalls when riding the a/f spikes then comes back to normal.
