Hard start, terrible sounds sub 32 degree weather
So its about 14 degrees outside today, and i went out to start my car to head to class, and the car barely started, even after it started it was running horrible, i could hear engine knock, lots of tapping, etc etc. I was wondering if maybe it had somthing to do with the gas perhaps, ignition system, fuel system, etc?

last night it was -10 and My car started right up again and usually in weather like this my car will knock for about 1-2 minutes, the oil I threw in today that I had sitting in my trunk was like molasses when I put it in, and it was even the smooth 10w-30synthetic stuff Wal Mart sells for $1.63 a quartthat usually flows real nice.

i just thought it was odd, seeing as how everyone elses car in the house, including my dads 93 cavalier with 210,000 miles on it, started up just fine, and my well kept neon didnt :rofl:

my Moms Cavaliermy Brothers Cavalier and my Sisters cavalier all make a lifter noisewhen cold but not as loud as the Neon is right away. The Cavys have a more traditional in block cam with push rods and hydroliclifters that cushion the knocking noise and reduce it. The Neon Engine is a better design less drag and better performance with the roller rockers.
My Neon also starts faster than any of those 3 Cavys put together. Get a good battery and check for broken vaccum lines that may have snapped in the cold.
The coldest weather I've started my car in has been -26 with a wind chill of -40 Farenheight, had to use. Good ol' Wisconsin!
A good battery makes all the difference in the cold and starting power.

once the car sits over night the oil slowly leaks out the hydraulic lifters creating lash in the valve train. Thiscan make the car run a bit harsh once started but once you get good oil pressure and the lifters fill it should go away. This is why it important to use the correct viscosity and a quatiy oil that will move thru the sysyem quikly and protect your engine at start.
anouther thing that will make that happen is your O2 sensor. when you sensor is cold it wont read as well, this is why they made heated sensors.
sometimes it can take a minute to warm up, then it will send correct info to the PCM.
