Did you ever get the "spark knock" problem fixed?

After the mechanic couldn't exactly figure it out however he was using my car as a guinea pig becuase he was working on an Infiniti SUV very similar to the pathfinder with the same problem. He didn't charge me for any work becuase i said it was okay to test out a few things. However it came down to a few things he said it most likely needed: either a new computer for the car or I had to get my entire car rewired. After that diagnosis, I decided to sell the thing and bought a subaru. I couldn't be happeir with my purchase and instead of the 14 MPG i was getting, i am up to 28 and saving money every month.

#12 of 12 1992 misfire

I have a 1992 pathfinder xe 6 cyl mpfi. 3.0 that has a miss under acceleration.
I've replaced the following:
spark plugs, wires, cap, rotor, ignition coil.
checked and fixed all vacuum leaks on intake, and for the emissions system, checked fuel pump for proper function.
ran codes on the ecu. everything is working properly.
put in injector cleaners. ( seafoam, etc.)
cleaned the MAF sensors.
checked all electrical connections under the hood, repaired the slightest crack or exposed wire. ran motor at night with no light, did not see any spark leaks anywhere.
it runs fine at low RPM's, off road is fine. once the rpm reaches 2500-3000 it has a misfire. when accelerating it skips and I can see the RPM needle drop for a second then go back. no check engine light is on. gas tank is clean.
with all the replacements my gas mileage increased but the misfire is still there. especially when climbing a hill on the highway. I live in Hawaii and there is always a hill on the highway to climb.
