I would ohm check the injectors with a multi meter. If the #1 injector is significantly different than the other three than you found the problem. The other possibility is the dark green wire is shorted to ground. All the injectors are supplied power by the pink with black wire. Each injector is then controlled by the pcm. If the dark green wire is not shorted to ground than a noid light would be needed to see if the PCM driver for that injector has failed allowing the injector to stay permanently on and essentially flooding the engine until it stalls.

Your problem is most likey your intake gasket.They have a problems on the SOHC engines where the intake gasket shifts & starts leaking vacuum at the #1 intake runner causing a missfire on Cylinder #1.While the engine is Idling buy some throttle plate cleaner & spray throttle cleaner down at the #1 Intake runner where the intake meets the head.If engine stalls or runs rougher that's your problem.I have replaced dozens of those gaskets for tha reason!! They have a beter design gasket through saturn parts.It has a coating on it to prevent reoccurance.Also you should check you Coolant Temp Sensor,if it's ceramic it's most likely bad.Replacement is brass from saturn.Good Luck

i would have to say first check the fuel injectors fuse in the under hood fuse block if blown replace it,sometimes the fuel injector harness rubs thru anywhere from where the harness comes thru the firewall all the way up to the injectors,,,if fuse is good and no bare wires to injectors,check the wires to the ignition module,,,,and if all checks ok,i would replce the ignition module,,you could have spark from it but it could not be sending the signal back to the pcm to fire the injectors,,,and if all that fails try a pcm,but i think youll find it before that,,i seen this 3 times and each time it was a wire rubbed thru near the fuel rail and it grounds out and blows the injector fuse,
hope this helped
