1997 Toyota Corolla Repair Question
Car jerks really bad when reaching between 50 and 60 mph after repairs

I forgot to add one thing which is the car makes a thump noise when this happens and I can feel it when my foot is on the gas pedal.
The jerk feels like a hiccup and feels like the car is lunging forward. I drove the car this morning and could feel this "hiccup" when doing only 30 mph, but when reaching 50 mph it is louder and I can hear like a thump and feel it, when I take my foot off the gas it goes away. The jerk is more like boom boom boom, there is a pause after every boom.
what about cap and rotor? were they new? lots of misfires are due to cap/rotor defects/moisture.
whan @ idle try misting watter from a spray bottle over the ignition system. dist cap and wires. see if this makes it run poor. if so i would start thinking ignition wires even if thay are new, dist cap / rotor and coil. have the wires checked well. thay are known to do this. around the boots. look for burn marks. i also think you may want to bring this back to the person that did all that work. arter changing all the parts i would think this car should run well.
I took my car back to the mechanic who claimed my car was jerking on acceleration due to poor gas, when i got it from him I din't drove much so I couldn't tell if the car was fixed. I drove the car the next day and the jerking was still there. I'm taking it back one more time and if not corrected I'll go to a Toyota repair shop.
I'm not a mechanic but work in IT and know that if a problem pops up after working on a computer, it might be due to the last thing done on the computer.
try disconnecting your EGR and see if that solves it.
