    Temp. gauge was going back and forth. Then it went to hot side. Is it a cracked block?
    Mechanic said it was a cracked block bec. coolant is running out the back of the engine. Does this sound right?

      The smoke sounds like an exhaust leak and maybe burning oil too. That won't cause your vehicle too stall. With a vehicle that old I would just keep fluids in it and drive it til it dies for good.

      The White Smoke is most likely from a head gasket, if the smoke
      is going out the exhaust pipe

      If not then a big coolant leak that is getting onto the hot exhaust

      1. Loss of coolant because of a coolant leak is probably the most common cause of engine overheating. Possible leak points include hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, automatic transmission oil cooler, cylinder head(s) and block.

      Make a careful visual inspection of the entire cooling system, and then PRESSURE TEST the cooling system and radiator cap. A pressure test will reveal internal leaks such as seepage past the head gasket as well as cracks in the head or block. A good system should hold 12 to 15 psi for 15 minutes or more with no loss in pressure. If it leaks pressure, there is an internal coolant leak (most likely a bad head gasket but possibly also a cracked cylinder or engine block).

      It is important to pressure test the radiator cap, too, because a weak cap (or one with too low a pressure rating.

      2. Air pockets trapped in the cooling system can cause the engine to overheat. Some cooling systems have air bleed valves built into the system to aid in the removal of air pockets. Advice: For many cooling systems, the method of removing air pockets is to start the engine and allow it to run with the radiator cap off or loose until all the air escapes from the neck of the radiator. For some systems this method is not sufficient, and the manufacturer has installed air bleed valves usually near or on the thermostat housing.

    My Pickup will idle very low and almost stall out.
    The engine will idle at about 600-800rpm, then almost stall out at 300-500rpm, then goes back to 600-800. The timing of the fluctuation is very consistent. I just put new plugs in last night but it was doing this before I put the plugs in. It is a manual, at the low ...

      My 1991 Isuzu 2.3L truck is doing the exact same thing, except it is also idling very rough. It stalls most frequently when I am decelerating. I found one cylinder misfiring. Replaced all plugs, sparks, distributor cap, and rotor to no avail. Did you find the answer to this problem? I'll post if I can figure this one out.

    I keep getting a link error on my code reader. Connection is good.
    Previous owner changed ecm so I don't know if it was programmed or not. Also just replaced fuel pump and no power when turned over. Last one did same thing. Any suggestions?

      Did you test drive the vehicle before you bought it? Please tell me, you didn't buy a vehicle that wouldn't run?

      The generic info says if you replace computer on vehicle 96 or newer, you have to have it programmed by dealership.

      As far as the datalink connector, generic obd2, pin 16 has to have voltage or the code reader won't work.
    • jdl

      Just to add, pin 16 gets voltage from horn fuse. One way to check if computer is awake, check for ref voltage at any sensor that uses a ref voltage. The ref voltage usually goes hot with key on.

      The problem was the ecm. Opened it up and found a burnt spot. Checked grounds and looked for shorts. Replaced ecm and rodeo runs like it is new. Code reader works great and power to the fuel pump.
