the idle should be about 900 RPM in park or neutral.
check your timing & up your idle a little
A vacuum leak (Brake booster).
Normally when you park it isn't moving therefore 0
Park on a transmission is a gear that allows the transmission to idle as if its in neutral while locking the drive train to prevent the vehicle from rolling.
It is normal for the RPM to increase a little when put in park or neutral. If the RPM increases by a lot, then you need to adjust your idle speed.
No load in park or neutral 700 give or take 50rpm With A/C around 800rpm
Could be a very dirty fuel filter.
Idle is set automatically by the PCM utilizing sensor on th intake manifold to limit the Idle Air Control Valve. If any of these sensors malfuntions or unfiltered air is entering the manifold, your idle will be up and down continously when in park or neutral.
The proper idle speed for a 2000 Nissan Frontier V6 is between 700 rpmÊand 800 rpmÊin park or neutral. In gear, the idle speed should be between 650 rpm and 700 rpm.
yes u can I've done it but i have a high idle issue if the car is in park or neutral.
It is a switch that only allows the starter to work when the transmission is in neutral or park.
if the ac was on it could lower the idle down the ac takes about 12 horse power to run + As long as the transmission is in "Drive," it provides excess strain to the engine system and at a stop will keep the engine idle a couple hundred RPM lower than in "Park" or "Neutral."
Not certain what question you are asking; normal idle is 750-800 RPM hot, transmission in park (AT) or neutral (MT). Cold idle can be 1500-2000 RPM. Idle speed is adjusted at the trhottle body; remove the rubber plug, turn the screw to increase or decrease as required, when the engine is warmed up and in park or neutral. A wandering or hunting idle may be indication of a worn throttle body butterfly valve shaft; poor fuel pressue; vacuum leak; or worn out throttle position sensor, etc. Good luck Malcolm
this problem could be your mass air sensor, or the problem i had when this happened to me was the catalytic converter is breaking apart on the insid clogging your exhaust.
My 1998 Park Avenue would not idle. I cleaned the Idle Air Control Valve (IAC) and the cavity it fits into with carb cleaner. Now it works fine. My 1998 Park Avenue would not idle. I cleaned the Idle Air Control Valve (IAC) and the cavity it fits into with carb cleaner. Now it works fine.
I would look for a vacuum leak.
If your checking the level of the tranny fluid in an automatic you need to turn on the engine let it idle in park NEUTRAL and pull the dipstick.
Your Idle air control (IAC valve) is probably sticking. Try cleaning it. If it idles too low, replace it for about $43.00
neutral safety switch
What is it?
The year, make and model would help.
Idle control motor defective.
In park the park pin is engaged to prevent the vehicle from rolling away. In neutral there is nothing to prevent the vehicle from rolling away
A tune up may help yes, but this also may be an idle problem. You can try adjusting your idle, and put a new fuel filter (s) in it.
