I was moving the arm switch for my water injection, some of the shink warp peeled back, and when I went to start the car, the wire coming from the B/W igntion wire touched the chassis, and blew the igntion fuse.

Removed the swiched that had caused the short, and covered where I had tapped.

Put a new 30amp fuse in, now the car hardly runs, will not rev, and throws P0300 for Multiple Cylinder Misfire, and Random Misfire Detected.

There is also as relay clicking for about 1 second when the key is turned

I checked the MFI Relay, and Fuel Pump Relay, and both are fine.

I took my ECU apart, thinking it might have gotten a shock, but it looks, and smells just fine.

I'm stumped as to what to check next. Any suggestions?
 
Don't mean to bring this one back but I'm having the EXACT SAME PROBLEM! Any luck with fixing it?
