      It is possible that your blend door is faulty. If possible diagnose your vehicle with a scan tool to verify if you have a stored trouble code, the trouble code will help you find the fault in your vehicle’s problem.

      Usually PCV valve is mounted on top of the cylinder head cover. Examine the cover, and look for a hose that is connected from the cylinder head to the intake manifold. The valve is inside the cylinder head cover. PCV valve is usually replaced along with the service change of spark plugs.

      You need a new fuel pump module assembly. It comes with the fuel pump and fuel level sensor both. Buy ACDELCO only.

    A loud knocking noise coming from bottom of engine.I checked it,s not the crank or rodbearings .

      Did you conduct a clearance check for the crankshaft and rod bearings? If the rod bearings are worn or loose enough to make a dull, hammering noise, sooner or later one of the bearings will fail, and when it does one of two things will happen: the bearing will seize and lock up the engine, or it will attempt to seize and break a rod. Either way your engine will suffer major damage and have to be rebuilt or replaced.

      This happens due to poor oil change maintenance, low oil pressure, using too light a viscosity oil, oil breakdown, dirty oil or dirt in the crankcase, excessive blowby from worn rings and/or cylinders (gasoline dilutes and thins the oil), incorrect engine assembly (bearings too loose), loose or broken connecting rod bolts, or abusive driving.

      Have the clearances check and test the oil pressure; replace the bearings and the oil pump if needed.

    What causes the cars 3.3 liter engine to die when the vehicle decelerates and comes to a stop?
    When slowing to a stop, occasionally the engine will die. This has been happening for several years, and occurs with much greater frequency in warm weather, when temps are in the 90's. Until this fall, it NEVER died in cooler weather. If the engine dies as ...

      Try unplugging the electrical connector on the idle air control at an rpm slightly higher than normal idle and see if the stalling stops. if it does then replace the idle air control. If it is unplugged the idle speed will remain stuck at whatever rpm existed at idle at the time it was disconnected. So, the rpm cannot drop off and stall it.

      Check the wirings/connectors in your blower motor it might be loose. If possible check the condition of your blower motor it may be faulty by now due to normal wear.

    While driving, engine suddenly stalls and will not restart.
    When trying to restart engine it sometimes will start and idle roughly for a short time. If accelerator is touched at all the engine instanly dies. If left for a day the engine will start right up and run for many miles untill it randomly stalls again.

      For your oil leak, well of course we have to look for it right? Visually inspect your engine for any signs of wetness, also put a large piece of paper under your car and let it sit overnight, in the morning, check the paper for leaks and that will help you pinpoint the problem. Anyway since you told us that you have a bad oil leak, then you have to replace the gaskets around your engine, im not sure if you are up to the task or just leave the job to a mechanic.

      Now for the heating, i can only think of 3 things why it overheats

      1. Plugged radiator
      2. Stuck thermo
      3. Defective W. Pump

      Also, loss of oil in the engine contributes to overheating

      Okay, I just had a new water pump and thermostat put on. So, that leaves a plugged radiator. This makes since because it doesn't seem to be flowing from the reservoir to the radiator. How can I fix this problem? Would the intake manifold or heater core be possibilities also even though I don't hear of them often going bad? I looked up how to fix these and they look pretty complicated. My heat works but then it makes the engine light come on and car overheats and smokes.

      The Chilton manuals usually have vacuum diagrams. You can pick one up at your local auto parts store for about $20.00.
