This is my daily driver. I bought it with 98k on ,and it is now at 161k
It has always run great until recently.
It is a KA24E 2.4 4cyl 2wd.

It has good power ,and feels fine when cold. Once at operating temp it is lacking , and its most noticeable when leaving from a standstill. It feels like it has drive by wire with a huge delay while trying to build power.

Response is instant when cold.
Truck has new NGK plugs, NGK wires, cap ,and rotor.
Fuel filter is new.
New O2 sensor ,and coolant temp sensor.

None of these have helped solve the problem.
Truck starts perfectly ,and idles perfectly as well.
Does not seem to be misfiring at all.

Basically no power in closed loop operation.
Any feedback is appreciated.
Thanks.
