Default Sc300 Troubles Dyes out at very low throttle and extreme hesitation HELP

hey guys, my car has been acting up so much this past months,

just for a quick rundown

1993 sc300
100k miles
brand new timing belt, water pump, gaskets, tps, harmonic balancer
Auto
new plugs wires, distributor cap/rotor within 3k miles
ok so my car lately has had extreme trouble from a dead stop to 4k rpms and then it pulls extremely hard but anywhere up to 4000 rpms it feels as if the plugs are bad but i know thats not it.

Also when i start my car and slowly pull out of a parking spot it will die it like i stalled out in a 5 speed. also going freeway speeds if i give it the slightest bit of extra gas it wil buck and bog out.

also recently it threw an egr code but would it affect my performance that badly

my sc takes like 10 seconds to get to 60 right now and its embarrasing almost got run over today.

HELP

check out my thread:

I was having somewhat similar problems to what you're describing and it turned out to be that the pcv valve grommet was cracked and leaking fuel. That little piece affected performance so much. I was getting like 6 mpg!

So I suggest getting the egr code looked at and fixed. It could be causing you're problem. Check for any vacuum leaks.
