If the clutch has been replaced check the engine grounds and tranny grounds. you might be getting a change in ground when the clutch is pressed.

SOURCE: 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.

SOURCE: high idle stalls at lights code for crank sensor

Crankshaft and Camshaft Position Sensors Camshaft Position Sensor Engine timing is determined from the relationship between the crankshaft and camshaft. This relationship is maintained by a timing chain or timing belt. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. The Engine Management System (EMS) uses signals generated by the camshaft position sensor to synchronize fuel injection to the valve sequence and for the on-board diagnostic procedure for misfire detection. The EMS energizes the injector at or near the time the intake valve opens. For misfire diagnosis, the EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses Diagnostic Trouble Codes (DTC’s) should be stored in the EMS.
If the camshaft position sensor or circuit is faulty most engines will start. Some engine management systems will then default to a pre-programmed injector firing sequence. All injectors may be energized simultaneously or all of the injectors on one bank may be energized at the same time. If the CMP data is required for misfire detection and reliable CMP data is not present misfire detection would probably be suspended.
Related Symptoms The following symptoms can be caused by an intermittent wiring connection or faulty signal to the EMS:

  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Stalling on acceleration
Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms: No Start/Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit

Why is my 1998 nissan altima keep shutting off at stop light?


Does it lunge forward a couple times when stopping? (Acts like a standard that the clutch wasn't pushed in while trying to stop). If so There is a solenoid inside the transmission that may cause this. If not second guess may be that you have a vacuum leak somewhere. Does your engine run rough? Or High idle?

Replaced Throttle & TPS & now idles up and down and engine light on


You need to purchase all the factory manuals before you
work on OBD 2 Vehicles yourself

Have you not checked to see what the codes are?

1994 nissan altima sometimes sluggish at take off, high rpms when changing gears


This sounds like a slipping transmission , check the fluid level first and make sure its full, if its full then you have ****** problems and may need to have ****** rebuild done,

Another thing is to make sure the trans passing gear cable is connected at the throttle where the gas cable is.

2002 altima idling too high check engine light on


The first and easiest thing you should do or have someone do, is check under the hood for a vacuum leak, possibly coming from a cracked or broken hose. Check and inspect all rubber hoses, including the large ribbed hose running to the throttle body (Engine air intake from the air filter box). You can hear a leak if it is loud enough and will sound like a hiss. Your engine is idling high because of a vacuum leak.

Suspect an incorrectly adjusted throttle position sensor or base idle setting. Some workshops have a habit of adjusting the TPS or base idle settings to change the note of the engine and hence make the owner think that things are better. If your timing is adjustable, recheck that too and make sure that all checks are undertaken by using the correct manufacturers adjustment procedure. Remember, computers can only give the correct output when they get the correct input and if someone has messed with these settings, this will throw everything the cars computer controls, all to hell.

I have a 2006 nissan altima that misses while driving


Misses that occur only under load are typically spark related. Engines typically need about 8000 to 12000 volts of spark energy to idle, but under load and acceleration, they can require as many as 30,000 volts. Weak coils frquently can still make 10-15000 volts, enough for light cruising and idling, but insufficient for load. Further, a defective boot or carbon tracked sprak plug may fire normally at idle and cruise, but "arc" down a black carbon track in the plug porcelin under load. You should take the car to someone who has the equipment to propely examine misfires. Or if you really feel the need to do it yourself, you could try pulling all spark plugs one at a time( assuming you dont have a scantool or trouble code data to point you to a specific cylinder) and visually inspecting them. They should ALL be clean and dry and white all around. If you see any black lines or marks in the porcelin of any spark plug, replace both that plug, and the wire or coil boot attatched to it. If you dont see any dirty or wet or oil soaked plugs, you likely have a weak coil that will require scan, scope, or load testing to isolate. Most professional shops have the equipment to do this.

Hi, I have a 2006 Altima with 31,500 miles. Recently, the engine start shaking when car is Idle but I still feel the shake when driving or at red lights. My second problem is a weird loud (humming) noise...


You don't need to change the spark plugs since it has only 31.5 K. The plugs should last 60K. There is a an adjustment at the gas cable end at engine to increase the idle a little bit. You can increase rpm at idle to 600 RPM. Since your RPM at idle is low that why it is shaking at idle, red lights. Let me know it it is shaking at high speed ( 2500 RPM)
