v8 5.2l -- 20'' wheels

well for same reason the truck for some time now ,has no power,i mean i really have to push the gas pedal to go from start to 60...is just lazy....

i spent some money with this problem and still the same thing...

this is what i did:
-tuneup
-rebuild tranny
-changed o2 sensors
-change cats
-added flowmaster
-put new high performance torque converter (to run faster)
-we also have change some of the sensors (dont remember,names-is been like 2years ,truck is siting)

now,
we also did:
-engine rebuild.
but

after give me the truck ,it was goig the same way,lazy,no difference that we have rebuild the engine.
and i have asked them what did you guys changed when you have rebuild the engine? and they said that they have change the piston rings only!,,and they called that rebuild,,! so now i have to start from the beginning,i have to check the cylinder pressure,and also to do a leak down test. maybe that where the problem is,but i know the engine was running round,no cuts,last time i have started,and no oil eating!,no smoke or nothing.

and

normally when a engine rebuild is done do to no power,you have to change :
-pistone rings
-resurface the cilinder walls
-check the heads
and if the engine is down,check rod & main bearings,seals...gaskets...


does anyone knows if is there a sensor maybe that may not work properly ? that may cause a lose of power?

thanks
