Heyy! Welcome to the forum!

When my car gets hot it still does not want to accelerate. It used to only happen in extreme heat and today it is in the low 80's and the car will buck when I push down to far on the gas. It keeps going but I can only push the pedal down a very little or it just bucks like I was stomping the pedal up and down.
I have a new o2 sensor, coils, repaired leak in egr tube, egr valve replaced about a year ago. The idle is better than it was since I repaired the tube but still idles down to far after about 10-seconds. I have also had the fuel pressure checked recently and I was told it was good.
Any ideas ?

also wires and plugs are new.
