Hi

I've got a 1999 Pajero SWB 3.5 v6. I recently had the engine washed and now sit with a misfire. I think there might be some water in the distributor. The problem is I don't know where it is located in the engine. Could anyone please help me and describe where it is situated. Pictures will be awesome.

Thanks.

The 3.5 doesn't have a dizzy. It has coil packs.

The 3.5 does not have a mechanical distributor as such. The engine control module fires three coil packs via an ignition power transistor bank based on a bunch of input parameters (including engine speed, coolant temperature, crankshaft position). One of the coil packs services cylinders 1 & 4, the second services cylinders 2 & 5 and the third one looks after 3 & 6. The system is called the "lost spark" system, because each coil pack fires both plugs simultaneously, although only one of cylinders is on compression/power.

The coil packs are close coupled to the spark plugs on the lefthand bank of cylinders and the plugs on the right hand bank are supplied via plug leads.

I would suggest starting to look for your misfire by disconnecting the plug leads to the right hand side bank and drying things out. If it persists, then you might have to remove the coil packs on the left hand bank, but that requires removal of the air intake plenum as far as I know, so it is a bit of a hassle.

Be sure to route all the plug leads correctly, not just ensuring that they go to the correct plugs, but also that they are installed in the correct position in the clamps that hold them (the clamps have numbers on to show what goes where) and that they are not rubbing against anything metallic anywhere.

4ePikanini is to fast for me, as always...

I would drive it for a few days.
The miss seems to be as a result of water getting in where it should not have.
Driving it for a few days might just dry out the water.

Hi Guys

Thanks for the info!

I've had the issue since Monday night, and it has only slighty improved. I'll give it another day or two then to see if it will clear up by itself.

Thanks again, much appriciated.

I agree with Gerhard - this worked for me in my previous car. It has to get to operating temperature and stay there for a while. Mine took about three such runs (from cold) to dry out properly.

Try not to have running water on the engine when washing - if you HAVE to use water, set it to a misty spray, and work over the engine quickly. Best is to rather use a brush and/or damp cloth and light soap engine cleaner to wash the engine.

Although a clean engine always looks nice, water and electronics are enemies, and water always wins!

Hi Anton

Thanks for the advise.

I didn't have time to wash it myself, so took it to a car wash. I suspect they used a pressure hose. Will do the washing myself next time.

If they used a pressure hose, it is most likely that water accumulated in an "unwanted" place, but they could also have disconnected one of the many plugs in the engine bay - I suggest you check through the engine bay systematically.

Hi,
Are the agents the only place to get new coil packs and leads? I can't seem to find any info on aftermarket products.
