Okay working on a neighbors 550 outfitter , pulling a trouble code E-200 , NOT IN MANUAL and even the Mfg. cannot answer this question , figured it had something to do with timing due to timing chain being really loose and jumping gears , so pulled apart new timing chain and oil pump chain alligned timing marks . and piston wasn't in BTDC position, and with the keyways alligned did what manual said , so after pulling apart and installing all new IAT sensor , coil, and cleaning throttle body , pulling these codes 200,113, 351 , then I find out this machine was at a coleman dealership for 7 weeks and they just gave up , I can't do that , so if anyone out there can tell me what the hell a E-200 trouble code is will greatly appreciate it !!
