hi everyone i really need some help cause i have run out of ideas for what it could be.

i have a fiesta turbo (OFAC) running T3 701's and chip

the probablem is: i can only just get the car to start and when it does start it will only just idel as soon as i touch the throttle it dies, its so bad i cant get it over 1400rpm

so far i have done....

new plugs
new leeds
new ecu
took chip off
took 701's off
played with fuel pressure (then put back)

none of this has mad any difference

Please any ideas would help alot

Thanks

danny
