Car wont rev, wont idle and is fouling plugs..
Ok so finally got a spare stock motor in while the other one is built, but the pos won't run.
Can't rev past about 2500-3000, it just stutters and cuts out. Feels like ECU is in safe mode. I got plenty of spares so I've changed the AFM, I've changed ECU, I've changed the TPS, i've looked everywhere for vacuum leaks... I can't think of anything else??? I'm ready to light the car on fire!
Anyone have any ideas?
What should the voltage readings be across the AFM wires? I might try add a direct ground to the cable, but can't remember which wire is which.

Check the ECU error code to find out WHY its having trouble ?

Error code 12 - AFM circuit open or shorted.
Cozzm0 do you know what the afm wiring should be like so i can check the voltages and the ground?

So much for buying a second hand loom in "good condition". Bloody gumtree... The thing is a mess, absolute dumb ass wiring job! The AFM wire has been cut before or replaced and its not soldered or even crimped. Twisted together and taped over, with exposed wires touching the shielding wire. FML...

Hopefully that hasn't damaged the ECU(s) that you've been trying.

Cheers for the diagrams, all good now. Car revs lovely now. Just need to sort out my idle, not working well when cold. But smooth when warm.
