Fuel injected????
Check the fuel regulator assembly. Mine cracked going down the road and everything went to crap! Started backfiring, coughing, sputtering and so on. There's 3 pieces to it, about $70 in parts......

Clean the IAC orifice inside the throttle body. It gets dirty and causes the motor to idle poorly.

When you spray the IAC turn your ignition on and cycle it with the run/stop switch while spraying. Put the tube into the IAC orifice. Almost guarantee this will fix your problem.

If that doesn't work look at your Crank Position Sensor.

You can also rule out the PV/tuner...disconnect and see if it still runs like crap.
