hoping someone here could help cure a T25 small turbo escort cossie that's not feeling well. its has a strange "fuel cut" under heavy throttle/boost. it feels like fuel momentarily cuts out when accelerating hard, but goes back to normal when you lift off the throttle. also, i have a fluctuating idle for about 30 seconds when the engine's cold (goes up to bout 1500, then almost stalls, then goes back to 1500). and finally, the car when at normal temp on occasion won't start until the engine is cold. battery is good, starter is normal, and fuel pump is working. somehow fuel isn't reaching the engine.

i've replaced the spark plugs, fuel pump, map sensor, air flow meter and still the problems persist. any input would be appreciated.
