Engine holds its revs.

[Tony]

Had a bit of a look into this with a local MY14 MN, as mentioned above, they seem to flare much worse when software commands the EGR. I even took to the AIT with raw butane to prove this.

I was able to stop the flaring by attenuating two important sensors so is in the ECU's software.

Made very little difference disconnecting the throttle body or bypassing the electronic boost control solenoid (A stand alone boost controller was fitted for this purpose, NEVER BYPASS THE SOLENOID on these unless you know what your doing.)

[chrisdoherty87]

Yes Tony I figured it was ECU related also. I have however found the perfect fix for this. If you turn the stereo up a few clicks you can not hear the flaring

Morning all. Have a 2013 glxr and has a intermittent run on, it seems to happen more when cold but does happen when at operating temps too. I've removed the egr blank but it didnt make any difference. .... fuel economy is pretty average lately too. It will hold the throttle for about 1-2 seconds after I lift off...any ideas

Cheers

Assuming you're not getting an engine light, I would think the "throttle" flap may be sticking in a partially open position and/or the SCV may be faulty.

Quick points.
Take the inlet hose off the throttle and note the position of the flap - from memory it rests fully open.
Get someone to operate the ignition switch and the flap should go through a diagnostic motion.
Sack a shock dose of injector cleaner in the tank along with some two stroke oil - this usually gives me noticeable results. Ml3.2 m

Other checks would include reseating plugs around the various engine sensors and clean MAF and MAP port.

A Scan gauge or equiv would obviously be useful.

A lot of the MN's manufactured 13 and later are doing it. Search "flaring" on the forum for more info

[hammy]

Cheers fellas yeah I searched everything but flaring lol. No fault codes BTW

[biggibbo]

It's not a fault. It's something designed in these days, apparently to combat carbon

[hammy]

Yep found the appropriate thread. ... delete away mr mod cheers

[Cowboy Dave]

There is another thread on this subject in the platinum subscriber's area. Over there some have experienced improvements after doing the EGR mod - here's the last post as an example of what I mean:

The beast in my engine has definitely been tamed." Claws clipped","fangs filed"!
Without a doubt,this mod has gone along way to nearly completely removing the flaring problem I have with my engine.
To say the engine has been tamed seems to be the best way of describing the result.

Have read the above post however need more people with the flaring issue to instal this mod and report the outcome.
Tony may well have solved more than one issue with the advent of his product.

I just had my MN MY2013 serviced (30k at Bussellton Mitsubishi) and asked them to look at mine holding the revs and was advised all good just a Triton trait. Will ask Rules at Kadina when I am in town next and see what they have to say. Cheers Derek

My complaint to the dealer when told engine holds revs or even increases is normal, was how inconsistent my ute was sometimes it did sometimes not.
Well after doing nearly 5000klm I noticed the revving issue was still there but seemed to be calming down
Now since new I have kept an app to monitor fuel costs and always used caltex vortex and runs at 8L to 100km, a few weeks ago I needed fuel and filled up with shell diesel and soon noticed my consumption did not seem as good but the ute felt so much better to drive and no reving issue at all 8.7l to 100klm
Next fill back to caltex and after a while engine reving starts again but fuel consumption very good.
So at the beginning of this week another shell fill,i am half way through the tank and absulatly no engine reving at all and ute is running very smooth but fuel consumption is down again

Anyway I might run with shell for a few fills, then try caltex again and report back.

Cheers Robby

[bigjobs]

You know what? You might be onto something there... I have barely noticed this behaviour lately and my last few fills have been from Shell.

I'm about to fill up with Caltex tonight, so I'll see how that goes

Cheers,
Bill

[Cowboy Dave]

Funny this. I used to run vortex a lot but moved away after hearing bad things. I am convinced I can feel the difference between shell and caltex fuel but on an objective level I almost can't believe my own opinion. You'd think the fuel should all be pretty close to the same but every time I see someone with the same experience I start to think I'm not imagining it at all.

We need top gear to line up 3 tritons with 3 fuels.

[Tony]

Truth is, our diesel in Australia doesn't appear to have any strict standards.

I have sent a few samples away due to fuel system failures on other peoples vehicles (One sample looked almost black like sump oil) and they all came back........ well, errrrrrm, so called in specification.
So I then contacted a diesel specialist that we use for core parts and they pretty much said the same thing!

This doesn't really explain the taming of engine flaring unless they have been mixing paint thinners or ethanol with the pure diesel.

[flatcountrymick]

I have gone from a cruiser with a hd clutch to the triton. I just assumed I had to modify my driving?

[Cowboy Dave]

Funnily enough Tony that diesel in your tanks is some of the best I reckon I've ever had. That or it's those long straight roads near ulan that did the trick.

[AnOldFart]

So if it's now suspected to be fuel related, has anybody yet, tried adding a 300ml dose of Castrol 2T into a tankfull of Caltex Vortex on any of these vehicles that are experiencing this 'engine flairing' issue....???

[biggibbo]

I have a mate at work having the issue with his new triton, and we use vortex due to fleet card we use. We have tried the 2T (250ml) in his rig for the last few fillups to no avail.

[Robby]

Hi guys
As in my previous post where my ute seems to run better using shell rather then caltex vortex, well my last 2 fills have been with vortex and although I believe the engine reving has improved since new it certainly was there using vortex. Today I filled up with shell and within 30 km I defiantly believe my ute drives better with no engine reving. I am not mechanically minded but will be filling up with shell from now on as the drive feels so much better.
Cheers Robby

Would be interesting to know where the fuels from respective brands actually originate from.

That would be interesting

[Photoguy1510]

Anyone desperate enough to try something radical? Test the clutch switch in the engaged state. Now by pass it so that it is always in that state. Simply prevent the engine management system from knowing when you depress the clutch. Thats simple, im assuming they are trying to imitate double clutching the car to take the load of after gear changes amazing what they will do to keep co2 levels as low as possible.

[BusterMan2388]

Apologies if this has already been covered but I didn't know what to search to answer my exact question..

I have a 2014 MN GLX dual cab diesel and when it's cold in the mornings the throttle is very jumpy and it sticks so when you take your foot off the pedal it's as if the throttle sticks on temporarily? Now as I know these things are fly by wire it's probably a software / tune related issue but I'm wondering does anyone know why they do it and is there a fix for it? Once the car starts to warm up it goes away completely! I find it bizarre. So yea very touchy jumpy throttle and it's also sticky is the moral of the story. Any Links and/or advice would be greatly appreciated

Cheers

[furious]

Could be the way the erg system is modulating the throttle. Are you in Vic or a cold region? and does it happen worse on cold morning?

Mine is worse if it is cold and has not started for a day or more.

[insomniac92]

Hey mate, I have a 2013 GLX and think I know what you're seeing. It only happens for the first couple of minutes, if crawling along in first, it lurches a bit, and looks sort of like I can't drive a manual, definitely not the case!!
I learned to expect it and drove accordingly to prevent it, but I have recently put in Tony's EGR mod and it seems to have tamed it to a degree. Not sure if it actually has anything to do with it, but I think I've read others have had similar results.
Cheers
