My car does the same thing, except for the low oil... from time to time when I come to a stop I'll push in the clutch and it will randomly stall... I think its b/c my idle is not set high enough, but there could be a different reason...
Idling is what your car is doing when it is just sitting somewhere running. As soon as you press on the gas it is no longer idling. Your idle speed is the number of RPMs your engine runs at when you are idling.
Check the sensors, mine did the same thing and it was the sensors
The spark plug gap can cause the RPMs to fluctuate, while idling. The more probable cause of the fluctuating RPMs is a bad camshaft.
1# Sometimes due to a rich mixture of fuel to air ratio, which means that there is more fuel than air going to your combustion cylinders. 2# Sometimes you just have a plug that does not work well, so make sure you check all your plugs to insure that they are in good working order. So, I just bought a brand new mower, Briggs & Stratton, and it is idling up and down. It started doing it about a week after I bought it, so I changed the spark plug and it fixed the idling problem momentarily, then started doing it again. I googled it and confirmed that my mower is suffering from a rich mixture as you speak of above. My problem is....what can I do about that problem? Please advise me, anyone, thanks.
My '89 Accord just began idling like that. It turns out that two of the belts broke yesterday, so maybe your belts are on the verge of breaking. Mine has been idling like that for just a few days before the belts broke.
the clutch
Clutch throw out bearing bad.
The fan clutch is not functioning properly. Replace.
The clutch bearing or " throw out" bearing is going bad and will need to be replaced, take this opportunity to change the clutch as well.
Perhaps clutch throw-out bearing?
When your standard car is idling, it should be in neutral. If it isn't, that means you are holding the clutch in which will eventually burn it out. Save yourself some time and money and only use the clutch to shift. Otherwise keep it in neutral when you are idling.
Well, a transmission itself does not idle...the engine does. A vacuum leak in the engine will cause faster idling or slower idling depending on where the leak is. Newer transmissions do not use vacuum at all for their operation. Older vehicles used vacuum to help with the shifting of gears-automatic transmissions.
Bad lockup clutch in the torque converter possibly.
It means your clutch is dragging. It sounds like the clutch friction disks are worn and its dragging and making the chattering noise
A bad fan clutch, low on coolant, missing fan shroud, bad thermostat or a plugged up radiator.
At 35mph it runs rough. Also when idling it will quit running, sometimes. Does that sound like I need new spark plugs? How many miles are new plugs & wires good for?
The fan clutch may be at fault or if the fan shroud is damaged or missing may cause those syptoms.
