1995 Toyota Corolla misses after warming up

After warmup the car misses and sputters during acceleration. My mechanic replaced fuel filter, still sputters he checked fuel pressure and it was good/he replaced distributor/coil/module and checked computer/still same thing.I got some advice as to replace the tps or egr valve he could not find anything wrong electrically is this a possible fix of the problem. He also replaced the distributor/coil/module after it showed no problem. Any help would be greatly appreciated in these tough times. Thanks
