Car sputtering when idle

A number of things can cause the car to sputter when idle. the fuel filter may be dirty or clogged, there might be a leak in the gas line that is causing loss in pressure, the valve clearance may have been adjusted too much and need adjustment back, possibly due to interference from other parts, such as from valves from higher combustion chamber pressure forcing oil past a high wear point seal. the list goes on and would require a more in-depth diagnostics session. try having your mechanic do an inspection to see if anything emerges.

why is my car sputtering while idle?

idle problems
if it's just sputtering, then there's no gas flow – bad gas line or bad fuel pump. if you can't determine which one is the problem, replacing both will solve the issue.

alternately, do you notice any dieseling at idle? that could be caused by an electrical problem – if it diesels once and resets but doesn't die again, that means there isn't enough electricity getting to your fuel injectors. however if it diesels every time (or sometimes), then that means gasoline pressure lines are blocked because of rust build up due to lots of months without use during winter months.

if the car has been running fine for many years now, this symptom is usually a sign of

why is my car sputtering when i stop?

because your air-fuel ratio is off. the engine likely needs a tune up and the fuel injector cleanings to make sure everything runs smoothly and provide you with a high horsepower engine yet again. i recommend reaching out to your local car parts store, they will be able to help you appropriately.

what causes an engine to sputter?

the answer to that question depends on what type of engine it is, but in general the car needs fuel, spark plugs may be fouled, air intake filter may need changing or a vacuum leak which would cause the engine to flood.

the most important thing in order for an engine to function well and run efficiently is getting a consistent supply of fuel. sputtering really only presents itself when there's a problem with this process. there are two ways in which your car supplies its engine with fuel: either by compressing the air inside the cylinders so that it releases petrol at high pressure, or by injecting petrol directly into each cylinder through an injector nozzle. this determines if you carbureted or injected car respectively – i'm assuming
