    200 opti sport jet losses rpm after 6-10 seconds

    at WOT gets 5700 rpm for 6-7 seconds then drops to 5000

    cleaned injectors
    new reeds
    gone thru compressor
    checked tracer valve, regulators etc
    fuel pressure 95/105
    air pressure dead headed 128 psi
    cleaned air injectors fuel injectors replaced 1 cyl that tested low flow
    fuel pumps test good

    has spark on all 6
    swapped crank sensor with known good

    can cyl drop test at speed no effect on cyl 5 or 6 above 3500 rpm exept within first attempt at WOT where its holding 5700 before it falls to 5k


    cyl 6 has the new set of injectors and has been issue since beginning..



    missing something seems sensor or electrical as mechanicals are sound running out of ideas here

    I'd try a coil on # 5 or 6 . Also take a good look at the 5 pin where the harness plugs into the coil. We have seen them melt together there. If you have a temp gun ,I like to check the coil temps ,it's a good way to see if anyone is dead . Are you looking at air and fuel psi at wot ? Have you looked into the jet pump stator veins and impeller ? Make sure the shift gate is not dropping down a little at wot . hf ...
