Post subject:  Coil problem maybe?
Folks, have a 05 Jimny with a sierra 1.6 (apparently) bottom end and a 1.3 Jimny top end. (better compression ?)

Have had some issues with it cutting out once things warm up a bit. I have been searching the posts, got a mechanic to look at it etc. There were some issues with the alternator so I have changed that out but still no joy. The alternator is providing plenty of current 14V + so all good here.

The thing is EFI and has the twin coils. It has extractors fitted and the coils sit right above them. There is no heat shielding at all so things are pretty well cooking, we live in the NT. It normally runs for about ten minutes clean as a bell and then starts to miss and will cut out very quickly soon after. It sounds like it is dropping a cylinder or two and won't re start. Give it ten minutes to cool down and then away it goes again like nothing was wrong.

My next step is to put a couple of coils on it but would like some thoughts on the subject if you have them.

As I am a newby i better introduce myself a little. We have three susie in our family, an 85 Sierra 1.3 HT, it is now painted cammo hence the name Bazooka, it is a bit rough but runs fine if it is in a good mood. Pretty stock appart from 30" tyres. I met a few of your members when I had just bought it, it was canary yellow at the time. Joel and a couple of other boys gave it the once over a couple of months back when they had linked up for a trip to Dundee.

The second is a 05 Jimny, it has had a bit of work done to it, as above, aptly named the blue turd as it sits on 31" tyres, has a 2" lift and has a custom XC Falcon bonnet and an attitude to go with it.

The third is the newest to the fold. It is a soft top 95 sierra with a Corrola 4AGE intercooled turbo engine and all of the mods to go with it. A mechanics dream. Has a six point roll cage to go with it, this is my sons car. Has 200hp at the rear weels and is a weapon. I haven't thought of a name for it yet as I haven't had to try and fix the thing yet.

Our first family 4wd was an LJ 50 suzuki HT which dad drove from Perth to Elliot in the NT with three kids a two dogs and a trailer. Full length custom roof rack and no idea what we were putting it through. Bought band new in 1978. Now there are some stories. Interesting part is we drove it up the Gunbarrel in 1978 and have been in the NT ever since. It never missed a beet but it was a bit cramped and there was no such thing as aircon in them.

The Suzuki is a greatly underestimated car and I love them.

Anyway, sorry for the long post, great site, I am looking forward to catching the NT boys whenever I can so drop me a line to make yourselves known.

Cheers

John

Coils can and do shit themselves when overheated.
Try a heatshield or even just a wet rag around them and see what difference it makes.

The wet rags are a good idea for a start, thanks for the idea.

As for the head, I am not sure, the coils seem to hang out over the extractors a little. I am not familiar with the jimny engine and have not played around with the later model engines. I will put a picture up if I can work out how to make the files small enough. Bloody technology.

Thanks for the ideas.

What a week. Folks still no joy with this one. Not the coils, power is still good to them even when the problem is there. Thought it may have been an issue in the loom. Went through it. It has got me stuffed. Runs as sweet as until it heats right up. Then the first thing that happens is the tacho power drops out, motor still runs though but rough as and the stalls. Let it sit for a few minutes and then starts and runs sweet as. Maybe ignition?

Still can get my pictures small enough to post.

Open to any other ideas.

Just a thought are the plugs and leads anygood?? Is the head in good working order?? Is the all the computer stuff good?? Ie airflow thingy and stuff like that are the injectors clean and fuel pump all good?? just a thought I've got the same problem but I've got a carby and I've narrowed it down to the carb or fuel pump

Well it wasn't the coils. It was the Cam Position Sensor. After all of that. $80 and it is running like a dream. Go figure. Funny how common a problem is once your solve the issue.

Hope this helps somebody.

Cheers

The worst part is it takes five minutes to fix it literally.

Hi John. Paul here. Was the big fella in Joel's maruti. That 4age Zook sounds interesting! Is it out at Dundee or closer to town! Would love a look over.
