Engine Performance problem
1993 Mazda b2600 4 cyl Four Wheel Drive Manual 160000 miles
My truck sat for four months without running while I was overseas. Now, when I start it and its it cold, it runs great. When it gets up to temp, it runs rough and then eventually dies. After tinkering around I ran it again, but this time I had the lights, heater fan, and fog lights on and after it warmed up, it stayed running and ran great, but when I shut all the lights and fan off, it sputtered and then died. I have been told it might be either the throttle positioning sensor or the Idle air control valve. Also, is the idle air control valve suposed to have water running through it? I took of the hose expecting air and I had water come out when I started it. (Is this for Coolant reasons?) Also, I have found NO vacum leaks either.
