Sounds like a fuel mixture problem, probably running too rich if hunts at tickover and sometimes dies.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi, Sometimes when I drive my car it starts to rev up and down itself between 500-2000rpm. If I apply the throttle it sometimes cuts out. What could cause this?, it is intermittent. thanks Amolak Migration info. Legacy thread was 19103

POST 4Original post

could be a vacuum pipe loose or missing? Migration info. Legacy thread was 19111

POST 5Original post

Sounds like a fuel mixture problem, probably running too rich if hunts at tickover and sometimes dies. Could be caused by a loose vacuum pipe as Poon says, check all the tubes and connections round the back of the engine (not the easiest of jobs). To get the mixture set properly you need to take it to a garage with a CO meter. Just make sure all the pipes are fine before you get the engine tuned. Matt. Migration info. Legacy thread was 19128
