What causes rough idling on a 2001 Chevy Metro after the timing belt was changed?

Rough idling on a 2001 Chevy Metro after a timing belt change could be caused by improper timing adjustments, leading to a misalignment of the engine's timing. Additionally, issues such as vacuum leaks, faulty spark plugs, or incorrect fuel mixture can contribute to rough idling. It's also possible that sensors like the mass airflow sensor or throttle position sensor were disturbed during the repair, affecting engine performance. Checking these components and ensuring proper installation can help resolve the issue.


Will a weak cdi unit cause an engine to idle rough?

Yes, a weak CDI (Capacitor Discharge Ignition) unit can cause an engine to idle roughly. The CDI is responsible for delivering the spark to the engine's ignition system, and if it is malfunctioning or providing inconsistent spark, it can lead to poor combustion. This results in uneven engine performance, including rough idling. Other factors may also contribute to rough idling, but a faulty CDI is a common culprit.


What would cause rough idling flooding and white smoke coming out the tail pipe of a 95 ford ranger?

Rough idling, flooding, and white smoke from the tailpipe of a 1995 Ford Ranger could indicate several issues. Common causes include a faulty head gasket, which allows coolant to enter the combustion chamber, leading to white smoke and rough running. Additionally, a malfunctioning fuel injector or a dirty air filter could contribute to flooding and poor idling. It's important to diagnose these issues promptly to prevent further engine damage.

What causes rough idling in a Celica GTS?

I experienced this problem after my car was leaking motor oil due to old faulty gaskets that needed to be replaced. Apparently because of the oil spreading everywhere it reached the engine mount. The oil combined with the heat from usage caused to wear down the rubber portion of the engine mount. I noticed the rough idling was gone once that piece was changed. Side note: It also helps to make sure your timing belt is well calibrated to determine proper idling. ANSWER: Another posibility is a vacuum leak or an air leak between the MAF meter and the intake plenum.


Car is idling rough and then dies?

A car that is idling rough and then dies could have several potential issues. Common causes include a dirty or failing idle air control valve, a clogged fuel filter, or problems with the ignition system, such as worn spark plugs or faulty coils. Additionally, vacuum leaks or issues with the fuel injectors can also lead to rough idling. It's advisable to have the vehicle diagnosed by a mechanic to pinpoint the exact problem.
