Well, the fault diagnosis on the vvti engine appears to be working perfectly. Unsurprisingly I've got code 14. Ignition signal: No IGF signal to ECU for 4 to 7 consecutive IGT signals with engine speed less than 3000rpm.

Yes, thanks. I can confirm that. This morning I've simulated faults by unplugging sensors one at a time and the fault diagnosis with the flashing orange light on the dash has been spot on. This should really be added to the fault diagnosis sticky in the technical section as it doesn't cover vvti's.

I was thinking that earlier today, I'll give it a go tomorrow.

http://mkiv.supras.org.nz/techo.htm#ENGINE_CODES I tried it yesterday, the engine check light just flashed at a constant frequency which indicates no fault which cannot be right as I'm positive that I've got a fault stored in the ecu.

Hang your head in shame.

I've just been out for a drive tonight and I only got a couple of miles from the house and buiding up speed on the motorway, the main warning light came on and the engine cut out. Numerous attempts to start it without success,it would start for a fraction of a second then cut out again. I left it for twenty minutes and managed to get running only for it to cut out again a mile down the road. I got a tow the rest of the way home. What's happened leading up to this: About a week ago I started to get a misfire when accelerating hard and approaching 1 bar boost, the main engine warning came on for a few seconds then went out, it was okay when taking it easy on the way home. So I fitted new spark plugs and new coil pack connectors . I went out for a drive yesterday to see what it was like, I had a little misfire under hard boost but it wasn't that noticeable. So I decided to drive back home again. On the motorway when cruising back and every time I accelerated a little it appeared to misfire really badly when in sixth gear. I've been checking all the connections on the coilpacks, sparkplugs and every other connection I could see on the engine before going out for a drive this evening and it cutting out altogether on the motorway. Any help would be appreciated, it's a right pain in the arse when you cannot check for fault codes on the vvti.

It was me asking the question. I'm still not convinced that it will definately work on the Supra as it's not 100% guaranteed to have a standard OBD II port. Like Chris Wilson says, " very few do, and they tend to be the expensive ones".

Thanks:) Over the last few days and I've been reading up on the Greddy Informeter and the Blitz R-Vit and they've advertised as being able to read the fault codes but I would like to hear from someone that've managed to use it on the supra before I spend any money on one. I've also been looking for anything I can find on the Supra's OBD-II port, you're supposed to be able to find out which protocol it uses by identifying which pins are populated in the port. They are 4,7,11,13,14 and 16 , but unfortunately they don't match any of the possible protocol's which are used for OBD II. VPW apparently uses pins 2, 5 and 16 .

A poor connection would give you an intermittent fault, I think the quality of the connection is related to how noticeable a misfire would be. If you unplug the connector itself and if the plastic bits including the white plastic piece break as the result of them becoming brittle this would mean that the two small female spade connectors won't be held in place correctly and when you plug it back into the coil pack you may get a bad connection. It's best to close gap in the female connector when you have access to them so you'll obtain a better connection with the male spades on the coil pack.

It's a pity you aren't closer Chris. I like do any work on the car myself and don't really fancy taking it to any of the local places.

You could always put one side of the car up on a high curb and drain some out.

Most of you will be aware that on the pre vvti cars you can use the paperclip method and short out the E1 and TE1 connections in the diagnostics port which will make the ECU flash the orange check engine light to indicate any stored faults. But the vvti doesn't have the TE1 connection. I found this on the New Zealand forum: The vvti does have the OBD 2 port but it doesn't use an accepted standard protocol so most fault diagnosis machines won't work, but it does have Tc and E1. Has anyone tried this as I've never been aware of it before today?

Yes, they are the same clips. I did mine on the VVTI last week.

My brother keeps telling us this as he works for them.

It's a long time since I've heard anything as gruesome as that. The only sensible thing to do would be to run away very quickly.

On the EPC there's only the two that you mention. By the time you read this though you should have the new tank fitted.

There's only 3 on the VVTI, it has 3 double coil packs.

I think so too, that's if you want the ones that screw into the metal bracket which is set in the aperture on the j spec car.

When polishing wheels you've got to be obviously aware of what you're polishing. Not all lips are chrome, some are anodised and you've got to be careful that you don't polish through it.

Normally it's slightly worse than petrol, around 85%. By brother has just fitted a kit to his S type Jag, the engine is much quieter as you're removing the noise from the petrol injectors.

You've got to be able to shorten some bicycle cables to a specific length by fitting new terminations on the ends. I had my brother make some on his lathe.

Personally I don't think there's anything you can do which will help you determine when the damage was done.

Time is a good healer. Ten years after "Merckx" died we got another cat, "Barney" was a stray who we took in. He's great, it's nice to give another cat a home.

Talk about pointless threads!
