    Random RPMs drop, engine seems want to stall

    Dominican Republic - sounds like summer all year. Here in Southern Germany we had last Tuesday the first snow and temperature is still at around 0°C *shiver* Say hello to the sun from me :) By the way, after doing all sorts of maintenance (filters, spark plugs, etc) I went last weekend to a...

    Random RPMs drop, engine seems want to stall

    The issue explained in the video - I never experienced on mine, but also appears to have not so much impact at all, at least not in my use cases. Even if it had, I would most likely not have noticed it so far. But it is good to know and look out for this issue. As for my LPG add-on: it is a...

    Random RPMs drop, engine seems want to stall

    Thank you very much for all those plots - now it is getting really interesting. As can be seen from the plot I shared your and my engine behave quite similar - at least when not taking your first plot into account. Man, this looks strange ... and a drop down to 300 rpms is somewhat scary (at...

    Random RPMs drop, engine seems want to stall

    Would you mind to do one more in N, just pushing it to about 2k rpm, then let go the pedal and capture the rpm behavior while doing so. (while it goes down or beyond 600 rpms). The engine should be warm though. That would be cool. And you are sure the first shoot you took, with the rpm going...

    Random RPMs drop, engine seems want to stall

    Thanks a lot mate! That is indeed helpful. I might need a bit of background The Figures 2 - 4 are more or less steady state, right? The first one is quite interesting, though. In that first screenshot did you come from higher rpms and the over-swing (to 521 rpms) resulted from that, or was it...

    2011 Explorer XLT - 3.5L V6 TIVCT Engine - Misfire - P0201, P0301, P0316

    Hey everyone, I am still starting to explore the forum, nonetheless - as I am facing meanwhile similar issues on my 2011 Limited - of course out of any warranty - I just would like to know, whether any of you has found some kind of fix on the issue? Or did you just dump the car? My issue...

    Driver Side Headlight Won't Turn Off

    Thank you Fritz, for the explanation :) - never stop learning. Wouldn't be the obvious workaround to switch it on/off manually as one used to, 20 to 30 years ago? Or is the 2018 missing that switch?

    Driver Side Headlight Won't Turn Off

    I totally agree, the anomaly you see, is certainly related to "logic-level" and the headlight is purely analogue. As I am foreigner - what does FOS means? As per my 2011 owners manual there is some configuration to leave HL on after removing key, but this should be a max of 3 min - not 10 min...

    Great, that would really help me. Thx so much.

    Random RPMs drop, engine seems want to stall

    This is of course the goal, such that relearning can start. All I am saying is that in the way to achieve this there are different possibilities obviously. As I am more on the safe side, I like it better to avoid the very dynamic way to do so, at least without knowing all the details of the...

    A favor - bitte - I need a "reference RPM FORScan" Oscilloscope capture

    Hello All, associated to a post of mine (Random RPMs drop, engine seems want to stall) I would like to ask you whether it would be possible for anyone of you to capture an oscilloscope reading via FORscan of the following situation of an older (i.e. non Ecoboost) gen V engine, and share it to...

    RESEOLVED !!! ford explorer 3.5 2011 Charging System problem

    @harencguri Maybe it is worth to list your tries here, so we need not to raise anything, that you have already done (apart from replacing the alternator, PCM, etc). Just an idea, that most likely has of course been checked already: when was the alternator belt replaced the last time, and did...

    Random RPMs drop, engine seems want to stall

    and yes, I did relearn the TB - but avoided the procedure linked in the video above. Reason is, that I don't like the idea of pulling the entire engine electronics return hard up to +12 V - instead I removed the return line only from the bat and left it floating for some hours - same effect but...

    Random RPMs drop, engine seems want to stall

    Thanks for your responses - Cleaning TB has been done. First no severe finding in terms of contamination, cf. photograph attached - state before cleaning. Second, cleaning did not help to fix/change the transient. OEM Part (should be Hitachi, isn't it?) would mean $190 (including customs and...

    Random RPMs drop, engine seems want to stall

    It appears I have a very similar issue with my 2011 limited. But it appears to be less severe in terms of the random drop - goes down to only ~500 not (far) below that. Thus I wonder whether there is a sort of "nominal" transient behavior with a "normal" drop and when does it start to become...

    Exotic - 2011 Explorer in Germany

    Hey all, believe it or not: I bought a 2011 Ford Explorer 3.5L Limited as used car here in Germany. My apologies for grammar & spelling - I am more into "globish" than English - as long as you understand what's the matter, I am content. This model has never been sold as new car in the...
