if it's a brand new take it back to dealer and demand they sort it out!
there's a number of things it can be from what I've heard, but if it's brand new sheesh!

It shouldn't be a permanent issue whatever it is.

Check the vacuum line for the boost control and make sure where it connects to the manifold is clear inside..

Try pulling the MAP sensor off and give it a hit with some MAF cleaner. It's hard to get it into the small tube, but did work wonders for my ute. Economy has also dropped by over 1L per 100.

Pretty weird for vehicles to have issues virtually off the lot.

Seems to point to manufacturing problem.

Our quasi nobility, instead of pulling Australia's pants down to let the Yanks and Asian entities rape us, should be working on getting 'lemon' laws in place and start some serious batting for the consumer.

With all the cost cutting going on around the world, it wouldn't be a surprise if components, such as SCV, etc, are getting through with less Quality control.

If the dealer has been willing to take your money and can't sort a problem in a couple of days then I'd be demanding a replacement or compensation. I said to a Hyundai dealer years ago, in response to their great 5yr warranty at the time, that I want to drive the car after I buy it, not come and visit it every few months on a hoist! :lol:
Don't let the b'strds get you down!!

First thing we do is a flow test on fuel return and also fit a temporary clear tube from fuel filter to the pump. (You should not do this if any risk of contamination)

Nine times out of ten the fuel flow will be poor and we find small air bubbles in clear tube.

Could contaminated fuel cause this?

Re: Carbon Build Up, EGR Blank, Catch Can Information

Postby Azza72 on Mon Oct 05, 2015 10:06 am

Hi, I'm new to this forum. Seeking advice.
I've got a ml 3.2 Glx/r, about 6 months ago had the problem of surging, no power, poor economy, blowing smoke etc. a mechanic sorted this for me, carbon build up in manifold etc.
$2300 later. Problem sorted.
Now though, it seems to have a bit of an erratic idle, some slight surging though still making good power, no obvious smoke, economy at 9.4, (std for my car)
Took it to a different mechanic for this problem, he said the airflow meter needed cleaning ?
Seemed to work for a while, now doing it again !
Any thoughts people ?
Anyone had similar ?
I'm not particularly mechanically minded, but want to be armed with right info so I'm not getting worked over by mechanic !
Would appreciate feedback !
Cheers
Aaron

Aaron welcome to the forum. I've moved your post to this thread, which is more specific to surging.

This can be a problematic one to solve, but have a read through the forgoing posts which should give you plenty of possibilities.
Chris

If work is so terrific, why do they have to pay us to do it?

My Triton has just started surging heavily while putting the foot down up hill generally going about 70-80kph. The car revs up and down wildly and sctually loses speed and cant recover. How concerned should I be? Its certainly not a fluttering like some of the others here. It's a 2011 auto glx.

1st change the fuel filter. If no improvement, its probably the SCV and will need replacing. Mine had the exact same thing happening. The fuel filter helped a little, however it was the SCV getting stuck.

Mine has a surging issue, started off doing it lightly when cold and around 2200 rpm, now it does it all the time and is creeping down the revs, cleaned the MAF. MAP and scv out but no change, changed fuel filter, blanked off egr but no sucess yet, pulling intake manifold off for a clean this weekend

Hi all,

Just new here today. I have read through the 14 pages on this thread and really need to clarify the definition of surging? In a few posts, some people have described a cyclical, vroom, vroom noise and others have described bunny hopping and complete loss of power.

I have the rpm flaring/vroom, vroom noise commencing at around 30-40km/h under acceleration (the tacho moves up and down about 50-100 rpm) and it continues until I set a steady speed. Once I maintain speed at 60/70/80 I cannot notice it. It happens all the time during acceleration and doesn't appear to be related to the ambient temperature being cold or hot nor the engine being hot or cold.

Is this the same problem that people have been able to fix using the following list of maintenance tasks? New fuel filter, cleaning of the MAF, MAP sensors, replacing/cleaning of the air cleaner, checking rail plug, checking connections, using Castrol Active 2T in the fuel, servicing or replacing the SCV.

I took it to a Mitsubishi dealer yesterday (last serviced at 54k at the dealer I bought it from and now has 62k on the dial) and the stealer reckons that the car needs to have the manifold removed and cleaned, the injectors done, the tappets serviced as well as a 10k service and that this will be around $1800. They reckon that the previous owner hasn't had the car service appropriately (the 30k service in particular) and that the extended warranty that I bought will not cover any of the known sludge build up problems. The ECU was replaced at 58k and I blocked the exhaust gas just after this.

The problem was very mild before it went to the dealer for the ECU but has been getting more noticeable since then. While at the dealer they performed a coolant/computer update. Since then the fuel economy has gone from 512km on a tank (11L per 100km) to 450km (12-13L per 100km). Fuel filter was changed about 2000k ago but none of the other maintenance has been carried out…..yet.

What do you guys think?
cheers
Paul

Ok, firstly manual or auto? If auto could just be the hunting/slipping torque converter, as once settled on a speed stops happening. If manual, could be surging...
Manifold clogging/cleaning is a common thing, I had a partial blocking plate in until just after 60K on mine, didn't stop the problem, just reduced its' severity. I then ran Tony's SPV resister mod and a catch can, no further carbon issues worth mentioning by the dealer at 90k and was traded running sweetly at 105k. I had surging issues, first at 20k ish, replaced fuel filter, then got worse around 30k. Changed scv was good until 45k from memory, had repeat issue but this time was fuel rail plug. I then decided to clean all plugs/sensors (MAP,MAF and fuel rail) every 7500 and run a fuel additive/lubricant, no problems since then. Now have a PB Challenger, did same mods from new, no issues at 14k.
Hope this gives ya a bit of direction, can be frustrating chasing an intermittent problem like this..
