PLEASE HELP.. non runner after K&N filter fitment

[eunos ross]

Hi All

Having a bit of a nightmate!... finally got round to fitting my K&N filter today, all went well, piece of cake to fit and then i came to starting it.

Basically cutting a long story short, its a mk1 eunos and if i try to start it with the air flow meter plugged in, then it turns over but wont fire..... then if i un plug it and try again it starts first time and ticks over fine, but every time i go to rev it it just cuts out!

The one blonde moment i did have was that when i was taking the old air box out i actually un screwed the air flow meter body and exposed all the gubbins inside, i dont know if that makes any difference?

Please please help.... i need it running for monday

Which bits of the AFM did you take apart? Most cars won't run with that unplugged (at least not for long), but I have read that you can kill the AFM by removing the part the spring clip cable attaches to for example!

putting it in to my simple terms, as you look in to the engine bay i see the alloy box on the right hand side inbetween the big plastic pipe that goes to the other side of the engine and the K&N filter, this alloy box has what looks to be like a silicone based top on it that the plug for the AFM plugs in to, when i took the plug off i also unscrewed the socket for that plug on the AFM, it popped outwards about 1/4 inch and i could see lots of metal pieces inside, at that point i screwed it back in.

hope this all makes sense?

i also unscrewed that socket bit for the plug on the AFM and lots of metal bits popped out and didn't work again... lucky for me, i don't need the AFM anymore - i was only unscrewing it to see if i could use the plug...

I did the exact same thing when fitting my K&N! One of the wires in the AFM got pulled out by my ham fisted attempt to remove it. Easy to replace and cheap
