CUTS OUT GIVING IT HARD THROTTLE

1997 Ford Probe

Engine Performance problem
1997 Ford Probe 6 cyl Front Wheel Drive Manual 122000 miles

i am a mechanic myself but this probe has got me baffled. It starts and idles fine, and if you rev it up slow it'll rev up fine. But if you punch it, it'll hit like 2500 rpm and cut out. Our scanner won't connect to the computer, its got a new distributor, replaced the TPS, fuel pressure is good, spark seems to be able to jump a good sized gap, we checked back pressure on exhaust, replaced o2 sensors, checked cam timing, everything seems to be in order. Any thoughts?

It sounds like you have hit about everything. Have you checked compression?
