rough idle and engine run.. bad injectors??

[c_k06]

my friend got a 92 gs turbo front wheel drive. it melted the ground to his number 1 spark plug so he changed it. it runs very rough and dosent have much power. i stuck a screw driver on the number 1 injector and did not hear anything so i did the same to number 2 and heard it clicking like its supposed to so then i went back to number 1 just to double check and i did not hear anything but im still not sure its a bad injector. what else could it possibly be???

Measure the resistance of the injector to start. It should be 2 - 3 ohms.
If it measures good then check the connector and wire. You can swap it to another cylinder and see if the problem follows the injector.

Run a compression test to make sure the cylinders aren't also damaged.
