The best # on the dyno logged 184.5 hp @ 4,785 rpm / 211 ft lbs tq. @ 4,350 rpm. fuel air ratio sucks (very lean) at 14.3 (should be 12.5 +/-) These are some terrible #'s IMO and the opinion of the Dyno tech...
Here are the possible causes from the book:

Restricted Fuel Supply
Fuel Strainer
O2 Sensor Circuit
02 Sensor Ground Circuit
O2 Sensor Heater Operation
Manifold Absolute Pressure Sensor Operation
Engine Coolant Temperature Operation
Engine Mechanical Problem
O2 Sensor
Fuel Pump
Fuel Contamination/Exhaust Leak

In addition, my own input: Knock Sensor. and/or Fuel Pump – I had the fuel pump problem with a Honda many years ago... in the mountains the car would only run up to an RPM… losing power until it drop back down to a lower RPM… no one ever could figure out what was happening with the engine. One day I replaced the electric fuel pump with one I purchased from the salvage yard, and would you know it, the problem was fixed.

By the way I got my letter from the VA... yes other people now have my social security number, dob, full name, home address, time in service, if I can see with both eye and so forth... so watch your back Vet. Hooah
