My 03 S60 non-turbo is all the sudden having massive throttle delay. I know that ETs have a 1 sec delay, but what im experiencing is worse.

For example, I stop at a 4 way stop sign, step on the gas, car creeps slowly forward and 3 seconds later the RPMs start to rise.
It feels like if people were pushing the car at the beginning, and then the car took over 3 seconds later.
Its scary when making a left turn without a green arrow light.

I unplugged the MAF, no dice, behaves the same. No CEL,

Hope to find the issue with your suggestions

 

Check tps sensor make sure it's working and not gauled. . Foot feed most likely a delayed response ???
It's EFI related most likely. Especially if it idles and runs fine!
