Hi!!

I didn't see you checking Coils, Ignition Timing, TPS, IAC Selenoid, MAP Sensor, Alternator Output Voltage, Vacuum Leaks, Cylinder Compression.

Let's check those things and we go from there !!

Good Luck!!!

Sounds like you need to replace your throttle body. Maybe just the seal on the base. Really no way to check other then replace, But if you do replace make sure they change the gaskets along with it. Good luck to you, You may get a good one from a salvage yard to test it out,
