hi all im new on here and need ya help. I had my saff cos 4x4 on the track in norway ( its great by the way you should come over next year to gatebil) The car after the first day ran ok, but on the way to the track the next day it was fine when cold but when warm it got harder to get the gas on until it stopped totally right at the gate to the track damn. Later it start fine again then when warm died. Think its the ECT sensor giving a cold engine message to the ECU. What do you guys think. Car is running stage 3 collins chip greens 3 bar collins 31 act, rs 500 intercooler plus turbo after cooler, grp A cone and coil, motorsport leads. 1.3 bar boost on t3. Im english but work over here. Cheers steve

 

ECT, most likely, also could be ACT, pressure reg, or map to name a few.
To check the pressure reg, suck on the vacuum pipe to see if you can suck petrol as the diapragms sometimes split, if you can such petrol here it is gone duff.

Thanks Tabetha i will check that, just gotta get car home as is stopped 2 hrs away. Local ford garage has took a quick look and they reckon its something to do with the dizzy so that must be the phase sensor. Thanks again.

 

The phase sensor if the original one may have killed it's insulation on the wires as they all do, later ones are much better and have red and blue wires instead of two brown wires.
Just a note the top wire on sensor(red) goes to the nearest connector pin, it is marked + but hard to see.
