I replace spark plug and wires ignition coil both injector and pig tail , idle very good but would die if you gave it gas check fuel pump pressure 10lb. I replace the fuel pump assy. Now I have 40 lb. Run well idle not smooth rpm bounce around 700-900 I can smell gas like injector are pushing to much fuel drive good but idle better with 10lb pressure i think if I could idle it up may help open to any advise also were can you buy the socket to adjust rpm

citi, the idle is adjusted with the TPS base and then flow setting. There is NO idle adjustment persay just with the D screw on the TB.

Sounds like the TBAP harness may be bad with that fuel snafu. If if has not been changed ..............it is bad. A bad TBAP harness will signal the ECU to pump to much fuel .. Yeah...They like to break wires where they enter the connection.

Check for stored codes..
