i have twin mercrusier 350 horizon's 300 hp 6.2l mpi, mefi3, port engine starts fine , will run at 1100 rpm or more, but when i put it down to idle at 800rpm
it stahls out after a few minutes, some times when i start it at idle it will run for 5 minutes until it stahls out, I put a new fuel pump and regulator in, new IAC, new TPI Swapped out the MAP sensor from the starboard engine as well as the ECM, new coil. any help would be greatly appreciated
Thanks cattom
