I know these have been talked about before, but I really wanted to verify.

First off the symptoms:
 Runs fine when engine cold, but really lumpy idle (eventually dies) when engine warm. Sometimes when driving off, the car hesitates, like it would get too much fuel, or like some cylinders wouldn't fire. Also poor pull if doing kickdown.

I used to have oily plugs and wells before, changed the gaskets to genuine Opel ones, checked plugs 1 and 3 (easiest access) and they are dry now. Also changed all the plugs.

So yeah, idle is f***ed up, so I checked the codes and got these. Now, is it certain that with these codes and veeery lumpy idle, that the problem is the crank sensor?

Oh, the car is 3.0 auto.

Thank you

When was coil pack and ht leads last changed?

[kluku5]

Last year around Christmas I think

[kluku5]

So what do You think, can the sluggish drive off be associated with crank sensor, or does it look more like DIS pack?

[Temetsy]

Check the resistance of leads and resintance of DIS pack. Sounds exactly same as when i had my DIS broken, threw up the "lambda open loop" code too..

The 19 is generally conclusive.

89 is rear multiram IIRC?

[Temetsy]

" 89   O2 Sensor 2 Open Circuit ". I thought crank sensor failure includes only difficult starting and cutting off? Might be crank sensor but still worth checking leads and DIS

[kluku5]

I remember someone here said that when cranck sensor fails it usually throws up the lambda code too.

I agree the DIS pack and leads should be checked. I did notice a drop of water around that area after it rained ...

But, don't go crazy, the cranck sensor I have at the moment, is not a genuine one, since at the time I bought it, I also needed a shitton of other stuff for the engine aswell so yeah

I think we've found the fault

crank sensor rarely throws lamda codes. It often throws a MAF code (73/74)

[kluku5]

Hopefully it's the cranck sensor though, it is cheaper and easier to replace, but the water drop still makes me a bit nervous. I did seal the plastic wiper cover thingy with silicone, some water still gets through.

[Temetsy]

Have you cleaned scuttle drains?

[kluku5]

Yes. Probably need to throw a bucket of water on the windshield, maybe I'll see where it comes through?

[Temetsy]

Yes do that, or if yoy have garden hose etc. it will be even easier

[kluku5]

I had a search and it seems that testing the DIS pack without special tools wont reveal much. I guess I'll just have to replace them both, starting from the cheaper one.
