Vacuum leak can cause this. Sometimes one of those rubber hoses, that range from three quarter inch and down in diameter, located under the hood can come off, break,or get loose at a connection. You sure want to rule this out first.

2001 Nissan Altima idling high in parking or neutral


I have the same problem with my harrier 3000cc car. We have changed the idling sensor, airflow sensor. air filter, we have had the throttle checked, spark plugs, wiring and nothing works. The smell you are getting could be from your gear box, have it checked out early and if the gear shift is noticeable then you will need a gearbox specialist to open it and change the clutch plates. Good luck.

-----------------

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

2002 Nissan Altima 2.5S high idle in park and neutral, press on gas-it goes down then backup. What should I do? Car has127k miles.


No idea to be honest without a good look myself and my trusty automotive meter but i would suggest that a possible cause could be the stepper motor ?? might need the valve part cleaned but if your unsure what to do then ask a local mechanic whos recomended by a friend or relative

What should the pressures on the low and high side of the air conditioner read ?


low side should be about 30 psi at idle speed, high side 120 to 180 psi depending on ambient temp. higher temp, = higher pressure, as you increase engine rpm to say 1000 low side should drop to 10 to 15 psi & high side should increase about 30 psi. If high side goes over 280- 300psi you have contamination (air) in system or over charged with refrigerant. you will need to recover freon, evacuate & recharge system with proper amount of refrigerant. If the low side drops below 0psi or into vacuum then the refrigerant level is low, you will have to check for leaks , repair leaks & refill refrigerant.
Hope this helps

Nissan Altima 02. heater problems


Have you tried asking them to just flush the system, as well as reverse flush? Sometimes that will clean it out enough to get you where it needs to be for now. If not, I'd try that, at another shop, obviously, if for no other reason, a second opinion. Try one that specializes in radiators if there is one in your area. If no luck, and your handy at all, I can tell you what I did to clean core out a few times that worked pretty well for me, and only cost me about $20-$30, and a little time. Let me know if your up to it, but I'd gamble the cost of a flush, and my method, before I'd pay $100's of dollars for new core.

High Idle


I have a 2001 Nissan Altima and mine did the same thing. We replaced the intake gasket. It costs around $5.50, but it requires several different kinds of tools. We spent over $100 in special sockets, etc. But once you replace that gasket, it will idle better.
