fuel psi should be 49PSI.....

and its hard to read alot of what you say....use english.

 

Thanks... dating myself there.

 

Oh no. not at all...... (where's my 'whistle' emoticon when I need it..... )

 

+1..............

 

sorry the truck when it is cold it is sluggish (no power) but not as bad when it is warmed up to temp. like it has the speed but not the power to pull like hills or pulling off hills like it crawls off them to me it doesnt seem to be the transmission because it shifts fine there is no slippage. i dnt think injector because i think i checked that and plugs where wet. and there was no code thrown when this started. also the guy saying about air cleaner i took that off right when it started happening and still was doing it

 

Plugs were wet????

Take it up to your local neighborhood parts store, ask them if they have a scanner that can read DATA. See what temp the PCM thinks the engine is.... (pcm uses a separate sensor from the gauge in the dash.)

If that checks out, do a compression test. Post your results.

 

ok i have it at a garage nw so when i he gets to it ill let u all know

 

ok alitte more info on this problem he check the fuel pressure and it is at 40psi and and as for the compression test he said that is it was that i wouldnt be able to start it as easy as i can and more help on this issue is there a sensor that wouldnt throw a code? hes looking at it for free so money in my pocket give me ideas

 

Loss of power stems from improper mixture, incomplete combustion, restriction in the intake, or exhaust systems.

Have you tried it with the O2 sensor unplugged? (to test the sensor)

Have you tried it with the O2 sensor removed from the exhaust? (to see if the cat is plugged)

If your fuel pressure is supposed to be 49, and all your are getting is 40.... that is indeed a problem. I have seen conflicting info on this topic though.... confirmation either way would be good.

Many sensors have failure modes that won't set a code. All of them, I think......

 

check your firing order..

who did your tune? Did it start right after?
