    My car is leaking antifreeze from the top of the engine
    It is a cold day

      The most common spot to leak is the 90 degree plastic elbow that connects the base of the intake manifold with the belt tensioner housing. Here is a picture >> https://www.google.com/search

      Also, if you do this yourself, make sure that you get the broken piece out of the housing and / or manifold or the new one will leak

    Why does diagnostic say Cylinder 1 is running lean
    Check engine light is on

      It does not say cyl 1 is lean. It says Bank one is lean, or code P0171 which can have multiple causes. Not a sure thing but I'd say replace the mass air flow sensor. Probability here is greater than 75%.

    Check Engine Light On - Code says Cylinder 1 is running lean

      Are you certain the code pertains to a single cylinder - rather than bank #1 - running too lean? The lean condition may be caused by any of the following conditions; faulty fuel injector, low fuel pressure, faulty fuel pump, cloged fuel supply or rail.

      What is the specific fault code? Please post a reply with the fault code for further assistance.

      I believe it was P0601 and the read out said bank 1 running lean

      The one thing you did not mention is if you checked the alternator WHEN THIS PROBLEM WAS HAPPENING? Bringing the car in for the alternator check when you already got past it will not confirm anything. It may need a new alternator but first check for corrosion at the battery terminals. On GM cars you have to remove the retaining bolt from the terminal and slip off the vinyl terminal covers.

      There is a procedure to find out. The procedure can be a DIY procedure but rather than me try to explain it and maybe leave out a few important details, I suggest that you Google the phrase "parasitic draw" and read procedures on more than one site that you find and digest methods used and select a site that you feel comfortable with the detailed explanations. Only thing that I will add is that the majority of all cases of battery drain are caused by a bad battery, even when the battery was checked by a pro and deemed good. However, if you replaced the battery and this symptom has remained then you can rule it out as a cause. Remember that even when the car is parked and not used, certain modules use a tiny amount of power at all times to keep them alive (but asleep) and given enough time sitting (not a week mind you) the battery will become run down. It is said that a drain of more than 50 milliamps is too much.

      unplug map senor.light will come on and engine idle won't come down from starting idle.make sure you disconnect neg.battery cable before you disconnect it,and engine off when re-connecting.can cause senor to fail if you don't do this and after re-connect it will take about 3 minutes depending on your cars computer for engine ligt to go back out. let it do by self not by OBD code clearing-computer has to adjust for this action

      not sure what you are saying Keith. what is a 'senor'? could you tell me step by step what to do so
      I don't have any doubt of what you mean. (i.e.) step 1-unplug map..? step 2- while idling disconnect neg battery cable...etc. this way I can figure out what you are saying, thanks

    Why does my car keep cutting off when the service engine soon light comes on.
    the vehicle has 60,000 miles on it. It cuts off after the engine gets warm and will start after 30 minutes of sitting but will stall after 50 feet of moving. Diagnostic code is P0128. I just notice that the gas is very low (60 mile left before running out of ...

      The P0128 fault code indicates that the thermostat is stuck open causing the engine to run too cold at all times, however, this is NOT the cause of your stalling. The cause of your stalling is *probably* a bad crankshaft position sensor even though there is no code for that.

    Why would my car run all day but at night it doesnt want to start.
    I am able to drive my car all day but at night it doesnt want to start. All it makes is a clicking sound.. WHY

      Please detail this clicking sound further. "clicking sound" is insufficient and does not allow me to conjure up anything. One single click? Repeated clicking? Origin of this clicking? What works or doesn't work when trying to start it at night? Lights etc? Did you try to jump start it? details....

      It needs a bettary is a greater than 90% probability. A battery terminal that is loaded with white or green corrosion is a 10% probability.
