Default 2000 Prelude sh bring up Misfire Code 74

I wanted to ask everyone on the prelude forum if they have ran into this problem before and knew how to correct it. I have basically done the following that the manual requires you to do with this problem.

Items Changed:

EGR
Injectors
Spark Plugs
Ignition Wires
Valve Adjustment
Compression Test

Has anyone else had this problem and if so what did you do to correct the misfire code. I am running out of ideas from what the manual suggest. The dealer has checked it out and costed me 250.00 and an independent shop has checked it out and costed me 500.00. HELP!!!!!

Change your fuel filter, if its clogged you could be running a lil lean resulting in a misfire, test you coil.

Sorry, this would help also with the posting the fuel pressure was checked and it was within spec at the delearship, so they did not bother to replace it. They recommended the injectors instead because of a circuit problem so they said. I have recently replaced the distributor cap and rotor as well.

Keep the suggestions coming..

Update:

Leakdown was very high in one cylinder 84 percent.
