Have a 99 Challenger 1800 with twin 787's. Just started having a problem with the starboard engine. At around 5200 rpm it starts to surge with RPM's falling back to 4000 then surging back and forth. Runs fine at 5k, just anytime it is pushed beyond that it falls off. Currently need to feather it to keep it there, punching it past 5200-5500 it will somtimes shutdown after surging a couple of times. Plugs look fine, scratching head on Raves, electrical, or fuel...
No problems on the port side.
Any thoughts would be appreciated.
