    no there isnt really a change in fact i have to drive a little then stop and it idle really low... around 500 rpms and the whole car will start to shake bad.

  • Neonjjm Jan 15, 2009

    my rpm's rise some, but it rises when i put the ac on or turn my wheels as well.

  • Neonjjm Jan 15, 2009

    when i brought it down to autozone they didnt see anything wrong when it cam to the ecu... hmmm and i cleaned out the idle air valve.. this is no fun :(

  • Neonjjm Jan 16, 2009

    it didnt come up with anything. they put a code reader into it and scanned it.. but it came up with nothing.

If there is substantial change going from park or neutral to drive, then the transmission is maladjusted. I could see this also causing the tranny to get hot if creeping along in traffic with frequent stops.
I'd check with your local BBB to find a reputable transmission shop so you can somewhat believe their assessment.

    It still sounds like the clutches in your auto transmission aren't letting go as much as they should when at an idle.
    If you stop, put the transmission in neutral or park, does or does not your RPMs rise? 

    Any shop will have a diagnostic code reader that would probably tell you what the cause is since most things in your car are monitored and then recorded if a device isn't as it should be.

    Another possibility is the Idle Air Control and if that is sick, it will have generated a code.

    Just got a reminder from another message; if you have an Autozone or Advance Auto Parts near you, call them and ask if they do free scans of your code reader.

    I didn't remember that since I bought my own a year ago for our family of cars.

    but it rises when i put the ac on or turn my wheels as well.

    This kind of indicates that the Idle Air Control is working although when you load the engine (give it more work to do), the RPMs should dip very briefly then rise again to ~700-750 RPM, the common idle speed.
    Both things you mention make the engine work a little harder; the AC compressor uses ~1-1.5 HP and the steering pump is a load as well.

    I really think you should have your ECU memory scanned to learn what is malfunctioning.

    Did Auto Zone actually do a scan on your ECU or did they just stare at it??

    The only thing I have left to suggest is to seek out a reputable transmission shop and jsut call them tell them of your problem and see if they think it can be transmission related.

Raceing idle

Hi Terry
yes you are right, your previous work caused the problem.
look for a disconnected vacuum hose somewhere from/to the manifold or throttle body, do visual check first with engine off, if you didn't see any disconnected hose, start up the engine and follow the hissing noise.
Good Luck

The 2003 neon alternator is actually controlled by the PCM, so swapping alternator is not possible, you have to add on an alternator and dedicate it to your stereo, I'm researching the same thing, I'll post my solution to this when I figure it out myself!

'03 Toyota Corolla 1,4 VVT-i 4ZZ engine idle rpm

Idle is factory set and cannot be adjusted, your best bet is checking for cracked hose pipework for air intake at idle,(not at problem under exceleration and driving) Any slight upset to the air /fuel ratio will be most prevelent at idle speeds.Check hoses where the meet metal flanges on manifold intakes and any sharp bends in ppipes.Good luck

Need to replace oil pressure sensor/or sending unit(getting low oil pressure idiot light when idleing in drive) 1997 dodge neon dhc 2.0L. I have a new one but cant seem to find where it is located on the...

In my experience with neon's the sending unit is most likely not the problem. I feel that you will find that the oil pressure is actually low and that the oil pump is going out. If you change the sending unit and it doesn't change then you will know for sure. The sending unit is located on the side of the block near the oil filter. It has one wire and simply unscrews and the new one screws back in and re-attach the wire. Hope this helps. Good luck.

1995 neon stalling and motor problems after left idle ing 10 min

I had a similier issue when I bought a used 95 Neon. Check your spark plug cables for worn surfaces. They like to rub the hood and the valve cover. When they wear down and heat up they discharge to the hood and v/c. This creates low voltage condition that causes the car to nearly die.
