It could be a vacuum leak in the throtle body or intake manifold. Get some carb cleaner and check it. Be careful as the cleaner is flamable.GoodluckJoe
Yes, "sparkling plugs" is definitely detrimental to idling or smooth running of an engine
Check your spark plugs and leads.
it could be your timing is off
Vaccuum leak somewhere
A bad exhaust will cause gas fumes to get inside the Nissan Maxima while it is idling. Gas fumes, if contained in an enclosed space, is dangerous.
I would say it is the cam sensor, that would cause more problems with the idle than the throttle body. Have it scanned for codes, if it is the cam sensor then the computer will let you know.
While driving my car died. The check engine, brake and battery light all came on. It did restart after about 10 minutes and died again 10 minutes later after idling for about 5 minutes. What would cause this?You have to take your car to a shop that can read the obdII fault codes. And then take it from there ...
This problem is in most cars, that is when running the AC on a hot day. There is a solenoid, or a solenoid and a valve to adjust the idle when the AC compressor kicks in so the engine will not die. My suggestion is check the vacuum hoses, as there is most likely one more more that are cracked or loose causing the problem.
i just payed $450 for mine and it has idling issues..searching for knock sensor location now...
my idling on my 2001 ford focus is not idling correct, tried to adjust idling but there is no screw or way to adjust why?
replace the carburetor idle speed electrovalve. Should pay about $3.00 for a new replacement part.
There are several things that can cause your 1993 Nissan 300 to idle rough. The most common cause is dirty spark plugs. Bad spark plug wires can also cause the problem.
A PCV or connecting hose problem can cause great issues with a 1997 Nissan pickup idling. In fact, this can keep it from running, even if it does start, and the engine turns over.
May be that one of the cylinders is not firing. Check spark plugs for oil/any other obvious damage.
A faulty camshaft can cause your 1991 Nissan Maxima to idle erratically. A diagnostic test could verify the cause of the improper idling speed.
A bent valve(s).
Because even idling engines use fuel.
I sat in my car in the driveway with the car idling, waiting for the kids to come out.
you have one or more cylinders not firing causing imbalance. check for spark at each cylinder.
change the mass air flow senser
water in the fuel can cause an idling motor to sputter and/or die.
An oxygen sensor, EGR valve or other tune-up related issue can cause a vehicle to stall when idling and in gear. Start with a computer diagnostic scan and see what it tells you to repair. You can often borrow, rent or buy a code scanner from local auto parts retailers. A scanner can pay for itself on the first repair.
Effectively all the fuel that it burns while idling. You are getting 0 miles per gallon while idling.
my 2001 Sentra would constantly stall when idling. My mechanic had a tough time diagnosing the problem because the "computer" kept giving the wrong codes. He ended up replacing the Mass Air Flow Sensor($250) and Knock sensor($170), and TPS sensor($100). Probably did not need all three replaced, but it runs great now. You could have them check those first.
