Fuel cut Help

A while back my car would just lose power as if i let off the gas and hit the brakes and i could floor it all i want, it wouldn't move. I swapped my PTU and it was done. Now, I adjusted my TPS and IACV and its back. I'm going to try tuning the TPS and IACV propperly. If that doesn't work, any ideas?

Did you fix it by re-adjusting the TPS and IACV

not really. if i keep the rpms steady at 2k it sounds like a misfire and wen i rev and the rpms come down, they drop down like 100rpms past idle and bounce back up to normal idle every time i do that. I dont know which wires to get the voltage from for the TPS either.

You gotta use a multimeter to check voltage at the middle wire on the TPS connector - not the connector on the sensor, but the gray connector below the sensor. Ground the other lead.

I stuck a sewing needle into the middle wire on the connector, then held the multimeter lead to the pin - you have to leave it connected. You have to look up the specs, its in the service manual and its all over the forums, but I can't remember off the top of my head.
