Asthmatic Mitsubishi

[The Stranger:Me]

SOHC 2.5 V6 engine (6A1).
You go to take off and if coughs, farts and wheezes for a while and remains generally retarded until about 2500-3000rpm. What’s wrong with it (other than being a cage, and a Mitsubishi)?

Water in the gas or coils.

I think its trying to tell you it needs surgery as it sounds like its in a bad way. Whens the last time it had a service?.

If you are asking here then you obviously don't have the necessary equipment to do a diagnosis....and not many here will either.Do the basics - plugs,leads,air and fuel filter....clean all connections.If that fails get the MUT on to it - at your Mitsi dealer.

Is it GDI? (Gasoline Direct Injection)? I've heard that the injectors go to shit after quite a few km's and needs them replaced. A mate's Legnum ran like you described till injectors were diagnosed, but that is GDI specific problem, not 'normal' injectors.

Could be anything, Throttle control sensor , throttle position sensor, Air flow metre ........
Save the guess work and go to a Mitsi dealer or anyone with a Snap On tester to get a code from it and then address the issue from there.
PS; is there an engine / trouble lamp illuminated on the dash at all ???

PPS; yip ... its a clear case of Mitsi shit rearing its ugly head im afraid, shoot it and save the planet and ya wallet contents.

Yer and if the H/P fuel pump fails , look for the invoice
that says $300.00 plus fitting please.
What a crapper huh.

[hayd3n]

check to see if there is any breaks in the hose goin to or coming from air flow meter
fix with duct tape or similar
it will be good temporary fix

Pleased to see I am not the only one who thinks this way.
Bling to Jim for the first correct answer.

Well I find that an interesting experience.
I initially suspect air flow meter.
I download the workshop manual, but am unable to test the airflow meter as I have no special harness, perhaps I could have bodgied something up, but figure I shall test everything else that I can first.
Test the air temperature sensor, test and adjust TPS and various other elements. Come to test the distributor. Access is shit and I don’t have adaptor for the loom so I can’t be certain I am testing it accurately. Best leave it to the professionals, they’re smarter than me at this shit.

So take it to the professionals, a Shitsubishi dealer, they’ll have all the special tools – or will they?
They phone back – it’s the air flow meter, that’ll be $595.00. Damn I say, but want it fixed so ok, go ahead.
Get a call back – they replaced the Air flow meter and the problem still exists, never mind they have tracked it down to the distributor – they think, so the car is not ready, but they’re working on it.
Turns out a coil has gone gaga, therefore it needs a new distributor.

The only reason I failed at these tasks was for want of the correct gear.
So what did I get for $88.00 an hour that was any better than the service I provide for free?

DAMHIK.

And you're welcome.

03 onwards Mitsubishi's in general are ok from my experiance, im glad we've dumped the GDI setup. They now are settling on mivec / turbo engines.

There is a Mitsubishi ecu scan that you could download http://mmcdlogger.sourceforge.net/ just need to make a cable. Should work for your model as i made one years ago for my 94 import mirage for datalogging etc.
