Hi I just bought this truck and I'm having a few issues understandably becAUSE IT WAS A SALVAGED VEHICLE. HOWEVER I GOT IT DIRT CHEAP AND IT'S IN exceptional SHAPE. So first off I removed my turbo and attaching hardware to get at the leak below, and found that the drain line was leaking and now I noticed more oil on the ICP sensor. I got the new drain line but now I'm waitin for the sensor and I'd like to know if there's anything else I should check. On start up the motor has a loping idle but as it warms it gets better. Fuel light's always on and the only time I get a fuel reading is when it's full but only reads quarter tank. Also I can't get A/C to switch from dash to floor. Please help my haynes manual wont do it for me. thanks
