Strange white ABF plug

[RadoABF]

Just a quick question, I was taking a look over my abf in my corrado today and looked round the back of the engine and noticed that there was a white plug just next to the drivers side with it not connected up, connector was lying next to it, it is just under the exhaust manifold, I followed the chunky wires back and they are all wrapped up and run along under the scuttle, get to the coil and do a u-turn and go all the way back and come and join up with what looks like into part of the loom.

Do you have any idea what this plug is or does?

My mistake It is black not white, have plugged it back in but can't see/feel a difference on anything

Was that plug near the throttle body the only plug what our describing sounds like the throttle switch tells the ecu when have released the throttle

theres also a plug which goes on the heated breather (not used in uk, only is states) it come from the engine breather at the front to the intake pipe near the throttle body, just plugs in but doesn't do anything, don't know if its any help to you or not

Thanks for the reply but it's not the tps. It's right down at the bottom of the engine on the drivers side next to the strut, I'm stumped!!

only plugs that side of the bay are, intake temp, brake fluid leve, carbon canister, tps, idle stop switch and heated breather, but there all up high. got any pics you could put on here?

Sorted it thanks mate, it's right down by the rear engine mount bracket, it was the lambda connector so explains why my car has been idling like bag of spanners. Thanks for your help man

Just about to say lambda but you already sorted it

Haha thanks Tweed
