Have you tried pulling the codes?

it studders when you go from part throttle cruise to WOT???? You need to clean your MAF & IAT in that case.

You should also make sure the TPS is getting around 4.5V at WOT too.

Totally agreed. Check codes. Clean MAF & IAT sensors with alcohol & q-tips. And check the TPS voltage.

Use a digital multimeter. You have to backprobe two wires on the TPS plug and turn the throttle wide open with the key on (engine off) and make sure it jumps to 4.5 volts.
