M42 running issues after hot start

[Jos]

This is a common one, there is a connector outside the loom wrap that controls where the ECU gets it's warm start information from (TPS or O2 sensor I think).
I have an e36 engine with loom and lambda however I wasn't aware of this when I swapped it so I have removed the connector and joined the wire together somewhere in the loom and rewrapped it. Does anyone (Brianmooore!:)) know what colour this sucker is and where it connects to as the hot start arsing about is just damn embarrassing!

edit:
I actually do have a lambda sensor so I think this wire should actually be connected, would this suggest the sensor is fooked? I think I also wired up the diagnostic plug for this so it should show up? and if I do cut it then the ECU will use the TPS instead?

[Jos]

could also be FPR or the leaky manifold confusing the O2 sensor, start with manifold and go from there

[Jos]

Manifold replaced, better but still messing about. Going to go with the O2 sensor is probably daffied, going to find the wire and cut it, no cat, no problem!

[Jos]

wire cut (I think I got the right one) no change.. bugger..

[Jos]

I shouldn't ever be a bomb tech - cut the right wire this time all is well now. It's pin3 on the AFM plug.

I wonder what the other wire was, didn't seem to affect the car at all lol..
