Disconnect your injectors one by one and see if t affects your idle

Check that oxygen sensor.

Check that oxygen sensor.

would that throw a check engine light

[brndck]

things to check:
maf
injector o-rings
o2 sensor (will not necessarily throw a code if its only working "ok")
spark plugs
timing
oil saturated with fuel
spark plug wires deteriorated?
fuel filter clogged

and so on. the basics.
