I'm with ryan. The compressor is working like it should but the bearings could still be bad. Now that being said I would take the belt off and spin the pulleys by hand and try to feel for a grinding bearing. Another thing you could try is use a mechanic stethescope and listen to the pulleys (don't stick it on the rotating parts but as close as you can to them).

 

Alright I will hopefully do this Thursday, but today my truck wouldn't start had to hold the accelerator down till about 1500 Rpms then in idled normally. I recently put new plugs, wires, cap and rotor and plenum so I'm thinking ingition coil or fuel pump my fuel goes down when I park on a hill, it was also 30 degrees last night

 

u shouldnt have to hold the pedal with a fuel injected engine man, if u do then the pressure aint building right.

 

I know that so would that be a pump issue possible? I know 30 degrees is no where cold enough to freeze gas but possible do something to the pump, or fuel injectors? I talked to a guy I work with he suggested the tps sensor I replaced this about 2 years about but not since my plenum was fixed I cleaned my throttle body this past weekend when I did the throttle body mod.

 

Sounds like fuel pump, but put a pressure gauge on the schrader valve to see what you've got going on for sure.

 

Figure out what is in your coolant overflow? The dark fluid?

 

No hopefully tomorrow since I'm off work I can empty it but looks like oil, you know when oil is in whateryou get that multi colored streak of fluid that is what this looks like. Hard to explain

 

Does it have a milky look to it? When motor oil gets in with coolant or vise versa it gets milky.

 

Holding the gas pedal to the floor on an injected engine puts it in 'clear flood' mode, and drastically cuts back on fuel.
