Question by  cheth (17)

Why won't my car idle?

It is fine if I am giving it gas, but when it idles, it just stalls and dies.

Could be a dirty fuel filter. Also could be the fuel pump or a leaky vacume line. Listen for an air leak sound replace any leaking line's. Would also do a tune up plugs and wires might help also. But start by checking vacume line's.I f it's an older car it might just need idle screw reset.

Your question is subjective, based on a number of things. It could be anything from a failed mass airflow sensor to clogged catalytic converters. Have a mechanic check it.


Answer by  icanoutfishyou (1148)

There's a number of reasons why your car may be stalling. More than likely it's some kind of faulty sensor, which could be a bad MAP, crank, MAF, or a number of other possibilities. Before you address them, get a tune up; new spark plugs, fuel filter, PCV valve.

It would be the Mass Air Flow Sensor (MAF), the sensor is not getting enough air and is clogged up.


Answer by  thudson (77)

Possible reasons for stalling at idle include a dirty throttle body, a clogged EGR valve, a faulty mass air flow sensor, or a vacuum leak.

My car starts ok but I have to pump the accelerator to get her to idle.

Consider a vacuum leak,if there is a leak too much air is mixed with your fuel,check all the small black hoses on top of the engine. also if your car is fuel injected there should be a "Check Engine" lite on the dashboard,have the "Error Code"read.
