Mitsubishi Repair: cylinder 3 misfire, fuel injector, capacitors

Question
Have a cylinder 3 misfire. Changed plugs and wires. Didn't change the coils. Everything is getting spark (i checked several times) thought it was fuel related and changed the fuel injector for that cylinder and still not running right.  It is definitely cylinder 3 having the problem. Was wondering what other possibilities it could be?  Could the timing be off and how do i fix a timing related problem?

Answer
Rob,
You should check your car's computer.  If you have a Mitsubishi made between 89-94 (and some 95's) had computers with under-rated capacitors in them that would leak over time.  You can read this article for more information:
