   What's the danger (if any) of not running any Lambda sensors? Am I just going to over fuel massively?
   
   On a 3-plug Vts.
   
   Engine warning light doesn't come on strangely...

   yep overfuelling, lumpy idling, misfiring and probablies hesitation on accelerating

   Cars not going anywhere, just need to run the engine for a bit tomorrow. As long as it not going to fubar the engine whilst it idles for a while.
   
   Cheers

   Didn't have any lambda's on the 8v for years.. Was fine.
   
   Also don't have any lambda's on the 16v, and that's fine.. I had lumpy idle at first, but it was the temp sensor.. idles perfect now.
   
   Only not running them.. as I bought a single-plug engine but needed to use a 3-plug loom, so didn't fit.
   
   But yeah.. it'll be fine

   I have ran no lambda sensors for about 6 months on a 3 plug vts, it runs fine apart from slight over fuelling, and it's a bit lumpy on idle but I think that was because of lumpy cams, not lambda

   i'm not using a lambda either. the only thing is the over fueling. no running problems at all. and no eml

   I'm only running a clean air lambda and it runs fine. Wouldn't say run it without for ages though

   how did you manage that only lamba sensor did not fit from 1 plug engine running it on 3 plug there is several plugs that dont fit?

    i did it to a vtr and got two jack plugs on inlet dont fit dont even have a wire there, oil temp and level, coil pack but all you do is break a little bit of the plastic away inside top right half square in corner that will fit then alternator but i just got one with a jack plug as my vtr one did not fit my loom, injectors just swaped over plug rail lol ideal way is i should of got a phase 2 engine then it would of plugged strate in as the 1.1 loom is exact to the vtr phase 2 loom not a difference ow well its nearly there now just waiting for my ecu to be sent back as its getting unlocked and then alternator and then pull my rear arches so i can fit my rear wheels on
