Hi, a friend off mine have a problem with his stage 4, 93' Escort Cosworth, it starts fine from cold, but it "dies" after a few seconds, unless he use the throttle. when warm it is ok(except it seems to be a bit lean under 2500 rpm). Map, cts, ats, tps, iscv tested and found ok..... Mainly it's under warmup the problem is pressent.....help needed
