Why is my Mazda 6 running rough at idle?

Really, your 6 will be running rougher at any RPM, but a misfire will be most pronounced at idle. Spark Plug Wires – While not every model and engine combination of vehicles today comes with spark plug wires (a lot are now coil on plug), if your 6 happens to have them, they can go bad and cause a rough idle.

What causes idle surges on a car ECM?

Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges.

What causes the Check Engine light to turn off at idle?

At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. The check engine light will randomly turn on and off even if the car is running smoothly without any jerks and stalling.

Can a bad throttle position sensor cause idle surging?

Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light

What happens when a car runs to lean?

Running lean, on the other hand, refers to when a car’s engine receives too much air and too little fuel. When this occurs, you may notice symptoms like sluggish acceleration as well as jerking.
