Hi all. I own a 88 Pajero NF with a 2.6 (4G54)engine. I need a distributor assembly as it is not running properly (revs not slowing down when stopping at the lights, lethargic pull until about 2000RPM). Mechanics had the engine checked out and the carby overhauled, so this is the next thing. Mitsubishi do not supply this anymore :hmm:. My questions

1. Does anyone know the part number of the distributor, so I can try to source it from OEM.
2. Does anyone know of suppliers in Australia (preferably sydney) for this.
3. Does anyone know a wrecker who might be able to supply this. Most I speak to don't know about it.

I tried to get the part number from Mitsubishi, but they wanted the 17-character VIN number (ie. JFNN...). My compliance plate and rego have the chassis number (i.e. NF....), so dead end there.

Would appreciate if anyone can help. I have owned this car for 20 years, and it is a good vehicle, if I can get it working properly. Thanks.

The distributor for the NF 2.6 are NLA through Mitsubishi and have been for some time - and when it was available it cost a shade over $1000.

That is a hell of a lot of money - worth more than the car. What is wrong with the distributor? If it is a weak spark, you could get a new chip for it, but if it was the spark quality, I suspect it would be weak all the time. My guess is that it is the advance mechanism if the problem is mainly at low RPM. Get hold of a timing light and watch the timing mark as you rev the engine. It should advance - maybe from an initial 10 Degrees to posssibly 30 Degrees at 3000 R/min. I suspect that this is the problem. The baseplate of the distributor will most likely move relative to the frame and the movement is controlled by small return springs.

There are 2 types of advance - centrifugal and vacuum. You can check the vacuum advance by removing teh vac hose from teh dist and sucking on it as the engine is running. The timing mark should move advance 10 Degrees. The centrifugal advance is controlled by small flyweights under the baseplate. The distributor shaft is in 2 sections - upper and lower. As the dist shaft rotates, the weights fly out and cause the top section of the upper section of the shaft (containing the rotor button) to rotate a bit (probably another 20 Degrees), thereby giving you centrifugal advance. It could be that you haven't oiled the pad under the rotor button and the top section of the shaft is stuck to the lower, hence no centrifugal advance.

It could also be that your problem with stalling at low revs is a vacuum leak somewhere - nothing to do with the distributor, causing the mixture to lean out too much. At higher revs, the extra fuel supplied overcomes the minor air leak and you don't notice the problem.

Loss of vacuum advance due to a defective/perforated vacuum advance diaphragm will also result in a vacuum leak.

Thanks. I'll check them out

thank you all for the infomation. The diagnosis of the mechanic I bring my car to is the distributor I finally this week was able to track down the Mitsubishi specialist mechanic who used to service this over 10 years ago (he's retired now and lives up Northern NSW but accepts work from time to time to keep sane) . When I described what had been done and the symptoms, he said it sounds like the carburettor overhaul did not go well, as the Mikuni carb on the Mitsubishi are quite complex compared to other carbs. As with anything, until he actually has the vehicle in front of him, it is only an opinion. I guess I going to have to take a long drive one of these days, wish there were mitsubishi savvy mechanics around sydney, and wish the parts were available.

These guys may be able to help out with a "Fuel Miser" carburettor overhaul kit:
