This maybe long, I have replaced timing chain,TBS,Fuel filter,ETC, fuel injectors, fuel regulator, plugs,wires,dizzy cap,o2 sensor. triple checked timing,that is dead on. no codes on ecu (55), compression is #1 160, #2 160, #3 160,#4 152. got good spark to all plugs, does not smoke, starts and ides fine, with no misses. I dont have any power at top end or on hills. seems to get worse as it warms up. truck has 140k miles. Have smell of unburnt fuel.. fuel pressure is good as well..Any Ideas,, I am at my wits end trying to firgure this critter out.
