What causes Nissan Altima engine to misfire at random?
Something is causing cylinders to misfire at random, which is a lot less cut and dry than a cylinder specific misfire code. The P0300 Nissan trouble code will trigger the Altima’s service engine soon light.

Altima P0300 OBDII Code Symptoms 1 The P0300 Nissan trouble code will trigger the Altima’s service engine soon light. 2 The vehicle itself may begin to run rough. It depends on how serious the misfire is. 3 The vehicle may produce excess vibration, especially at lower RPM conditions
How to troubleshoot a Nissan Maxima engine idling problem?
If it is significantly higher than this at normal operating temperatures, adjust the adjustment screw of the throttle cable counterclockwise. Check to see if your transaxle is clicking at idle. Even if your Maxima is not stalling, it is still suffering from a low idle speed. Tighten the cable to the proper engine idle speed.

What causes a Nissan Altima to lose power?
The power loss failure can be related to a damaged catalytic converter, which is a manufacturing problem that car model has. You can try removing the converter and your problem should be solved. Good luck. Altima cars have got oil pump and camshaft manufacturing problems.
What happens when you have a bad idle air control valve?
For example, if you turn on your heater or air conditioner when you have a bad idle air control valve, then your engine will probably stall immediately afterward. The steering wheel might also feel like it’s being dragged to one side too. To temporarily fix this problem, just turn off your heater or air conditioner to reduce the load.
Can a Nissan Altima stall at any time?
Stalls can happen at any time, and it can be incredibly jarring when it does happen. Before troubleshooting any automotive issue, including stalling issues with the Altima, make sure that you check the vehicles trouble codes with an OBD2 scanner.
Which is worse rough idle or perfect idle?
Very rough idle with a repetitive cycle that is smooth for a couple of seconds then misses badly, occasionally stalling. Worse problem is bad hesitation when accelerating after throttle at idle position, sometimes stalling. Worst after stationary idle, but also after moving at low to medium speed with closed throttle and then accelerating.
Which is the worst idle after a cold start?
Worst after stationary idle, but also after moving at low to medium speed with closed throttle and then accelerating. Also very hard to start because of periodic ‘backfire’ while cranking that brings engine to standstill. Idle is perfectly smooth for first 1 – 2 minutes after overnight cold start, before missing at idle starts.
What causes engine revs to drop when idle?
3) Once at normal operating temperature, the engine misses badly while idling. It idles smoothly for a second or two, then misses, which causes the revs to drop suddenly, and then the control system seems to increase the idle speed to counteract the drop in revs for a second, and then the cyle repeats.
Why does my Nissan Altima shake when I ID?
If an oxygen sensor goes bad, it can make your Altima run too lean (or rich). A super lean running engine will often shake when idling. The mixture would be wrong at all RPM, but as the engine speed increases the shaking decreases. 7. Fuel Injectors
What causes rough idle on an Audi A4?
Ignition Coil Packs – Nearly all model years and engines use coil packs. These packs are fired by the engines computer at exactly the right time to provide the optimal ignition timing. If a coil pack goes bad, it’ll cause a misfire and rough idle condition.
When does rough idle in Gear get resolved?
Last edited by jpjm132003 on Thu Mar 14, 2013 9:29 am, edited 1 time in total. Highly doubt this is a grounding related issue. First things I would check would be IACV and TPS. * By check I mean look to replace or clean.
Where is the throttle position sensor on a Nissan Altima?
Your Nissan Altima uses a series of complex sensors to report what is going on to the ECU. The ECU then uses this information to adjust the timing, air fuel mixture, and more. When one of them goes wrong, it can lead to stalling for sure. Throttle Position Sensor – The throttle position sensor is typically located on the gas pedal.
What’s the RPM drop at idle on a Nissan?
RPM about 650 down to 500 and slightly running rough. Take foot off brake (car is chocked so won’t move) and RPM back to 650-700 and no issue. Back on brake same thing. No Vac leaks detected (took it in and had checked) seems that I can pump the brakes a bit and it comes back like something sucking the vacuum but its not.
What’s the idle speed on a 1997 Nissan Hardbody?
I have a 1997 Nissan Hardbody with a 2.4-liter engine, manual transmission, A/C, and 89,000 miles. It idles at 1,500 rpm, which doesn’t go down after it’s warm. I checked all the plugs and everything seems to be plugged correctly.
Why does my car idle at 1500 revolutions per minute?
Older cars will try to compensate for worn spark plugs or a failing ignition coil by increasing the engine idle. An engine with a problem that is idling at 1500 revolutions per minute is far more likely to stay running than the same engine trying to idle at 800 RPM.

How do you fix a high idle on a Nissan truck?
If necessary, adjust the fast idle cam screw (A) until the alignment mark is centered on the lever roller. Start the engine and let it warm to operating temperature, or do the repair after a few errands that you needed to run anyway. Measure the clearance between the lever roller and the top of the fast idle cam using a feeler gauge.
What does it mean when your car Idles rough?
My car has 128000 miles. My car has an automatic transmission. This may be a sign of a failing idle air control valve. The idle air control valve is located on or near your intake manifold that monitors the air intake as it is mixed with fuel prior to being injected into the engine.
Why does my car idle with my foot on the brake?

How does a spark plug work on a Nissan Altima?
The spark plugs bridge a gap between two electrodes in the engine that allows fuel to be transported to the engine by the ignition of a spark from the spark plug. A distributor routes voltage from the ignition coil to the spark plugs. The distributor connects to the top of the distributor and contains a terminal that connects to the ignition coil.

What are the O2 sensors on a Nissan Altima?
The oxygen sensors that are equipped in your Nissan Altima are responsible for monitoring the exhaust to help the ECU determine the correct air/fuel mixture. Of all the sensors equipped in your vehicle, the O2 sensors may have it the hardest. They deal with super hot exhaust that can cover them in deposits that can leave them ineffective.
What causes a rough idle when placed in gear?
When placed into gear (reverse/ drive/ 3 / l2 / l1) and at idle, the engine vibrates enough to drive me mad. another forum suggested a grounding kit and I’m considering giving that a try. Are there any other things you guys could suggest to cause a rough idle when placed in gear?
Where is the distributor cap on a Nissan Altima?

Why is my CVT dying on my Nissan club?

Why does my Chevy Captiva shake at idle?
An engine misfire is the most common cause of a shaking idle, and as the engine stumbles and misfires, that should be seen in the tachometer as a drop in RPM. If the tachometer is rock steady, and the shaking seems worse in gear than out of gear, that’s a pretty good indication of a bad motor mount.

What to do if your Altima engine is vibrating?
To check for engine-mount problems, the mechanic may try shifting from “neutral” to “drive” and back, while the engine is running. If the vibrations disappear or reduce dramatically in “neutral,” it’s likely that you need new engine mounts.
Why is my Nissan Altima engine not working?
Loose or disconnected hoses on and around the engine (not the coolant hoses that go to and from the radiator) are frequently culprits behind intermittent engine operation. Very dirty or clogged air filters can also cause your engine to underperform. Loose timing belts are another likely cause.
