    MX 6.2 MPI idle issue?

    So.. Updates: Yesterday we adjusted the Ignition timing with idle mode A/B Jumper - ✅ Idle still fluctuated so I checked the MAP - it was on 1.39-1,6V up and down. So I THOUGHT I found the failure. Then I wanted to measure the TPS as well and was searching for the dark blue cable at the...

    MX 6.2 MPI idle issue?

    Thanks mate - I think I know nearly every MPI Video on YT :) . I will set the timing new next week with the base timing mode. But this seems not to cause the idle up and downs

    MX 6.2 MPI idle issue?

    Hi - I disconnected and removed it, there was abs. no difference. The thing is, that the idle is not stable in any position - floating 1,400-1,800 in „normal“ mode when everything is connected (or even disconnected) and 1,000 - 1,400 in Diagnose mode…. So you have this loose cable as well? I...

    MX 6.2 MPI idle issue?

    not in that detailed way: It is not possible to drive or put the gear in, the rpm are too high (of course I could push it put it "feels" wrong and it far to fast in the box...) which rubber tube do you mean? Thanks all, much appreciate. I organized a Mechanic with a Diacom - need to wait until...

    MX 6.2 MPI idle issue?

    I am just back from the boat after putting the engine in base timing mode again. Double checked: LED signals the Diag-Mode only as described above, no further codes. The Motor runs on 1,200 goes down on 1,000 goes up to 1,400 then back on 1,200 for about 5 sec. so seems that the sensors are not...

    MX 6.2 MPI idle issue?

    should mean that this cable is connected to the port side of the motor where other ground cables are connected as well (like the transom) already realised - the "flash - pause - double flash" is the only signal code - no further failure codes yes - wasted enough of money without progress...

    MX 6.2 MPI idle issue?

    Okay, MAP found - i will check. Hope to get a diacom shortly Transom is connected with a ground cable - connected to the same block where the lose one is coming from

    MX 6.2 MPI idle issue?

    Ok - looking into the part catalogue I can’t see a MAP sensor for the early stage MX 6.2, right? so if it’s not the TPS it sh/could be the coolant sensor?

    MX 6.2 MPI idle issue?

    disconnected the TB yes but closed IAC hole (not the whole TB) then motor shut off. What is your thought since you directly asked for the reaction after A/B jumper?

    MX 6.2 MPI idle issue?

    Hi all - thanks for all your input. I went to the boat and tested the A-B Jumper on the DLC. Result: Idle went down to 1200rpm as it should. BUT not stable. Really weird that with the first start today the motor stayed on 750 rpm for half a minute, then went up to 1,600. After warm up he is...

    MX 6.2 MPI idle issue?

    ok, good to know - it 100% kills directly when covered - so no vacuum check needed? no idea where to connect the tester which is on the way from amazon... I know, the question was, if it gets the right information from ECM when and how to open we should leave this topic - I really don't know...

    MX 6.2 MPI idle issue?

    ...and where shall I connect the vacuum tester? any suggestions?

    MX 6.2 MPI idle issue?

    Great stuff - I will try asap!! We def. did not do this. Last question on this: No. 4 says start the engine - number 9 restart engine. After which number I need to shut the engine off between 4 & 9?
