WOT misfire, please help

Hey guys ,my 89 350 tpi has been acting very weird lately,

it has a irradic idle hot or cold but drives fine during cruising speed and completly misses and backfires under wide open throttle

ive changed plugs, wires , o2 sensor and checked the injectors for leaks etc.

any advice is greatly appreciated. Thanks
