Right, I'll have to look at my settings tomorrow but they may be the wrong injectors selected... There should be a couple of options for AC injectors IIRC :-\

While you had the plenum off did you check the injector pipes weren't trapped? And have you definitely got the right injector pipes connected to the right injectors? :-\

If all else fails, it can be run on petrol until someone can help you out :y

Bear with it... It's fixable ;)

Ignore the warning as long as the lambda readings stay high ;)

It could still be HT related but need to check everything else first :y

Wiring is defo correct. Pipes are free. I've blown compressed air into the manifold and heard no difference. Just measured resistance on all six coils. Bearing in mind they are luke warm from the last run the resistances I was getting went from 3.4 to 4 ohm. Not sure if that difference in resistance is enough to throw it all to cock. I'm off to stuff broken glass down my trollies. Be less painful than this.

I think you might need to bite the bullet and get one of us to have a look over it with you. Walk away and have a break from it ;)

It's probably something really silly and simple so don't lose faith :y

I know nothing of installing this kit but i'm sure I heard someone mention that the markings on the loom for the gas injector numbers don't match the petrol ones marked on the fuel rail.

Just a thought. probably wrong though.

Yep ::)

I'd have to stop for a pee and everything  :o I've got to get this sorted by 12th of March. Got an operation coming up and I'll be in plaster for 4 months and this is the only car I'll be able to drive with my left foot all bundled up  :-[ :-[

Aye. I'm out of ideas. The two last things for me to try are. Gas injector selection and then drilling the jets to 2.5. Will try that tomorrow if Paul is able to tell me his configuration. One last thing. Could the gas ECU be frasseled? but more than anything I need someone else to look now. I'm out of ideas.

I wouldn't be doing anything as drastic as drilling injectors yet ....  you say it runs OK with an open throttle, so the injectors are giving plenty of gas anyway, at low RPM the injectors give less gas so drilling won't do any good, and could make it worse... IF (big IF and guess) the injectors cannot go "low" enough for low rpm ..ie.. because of the size and minimum opening time they are actually "overfuelling" ?? if they can do that ?? as I say  ... a guess and probably wrong ...IMHO it needs one of the experts to look at it and look at live data at the same time ... que Kevin :)
