"There's no such thing as a thick question, just those who are thick enough not to ask"

 

I'll try to simplify it as much as possible ok.

 

"Tickover" is when the engine is idling with no pressure on the accelerator like when you are sat at a set of traffic lights for instance thus the engine is ticking over nicely.

 

The "Lumpy" part to it is when the revs of the engine go up and down slightly but erratically without the driver doing anything, it should be smooth and as regular as possible.

 

The lumpiness can be symptom of various things like not enough or too much fuel getting through to burn in the engine on tick over or not enough air for it to mix with essentially starving or over fuelling.

There is always a reason for this and it is usually down to many electronic sensors not doing there jobs reporting back to the ECU (engine Brain) what is happening or the fuel system parts like injectors can be worn, dirty or slightly blocked amongst many other things.

The problem is trying to find the offending part, that is the difficult bit.

 

Lumpy tickover is not a bad thing in itself but it can giveway to more serious problems like "flat spots" when a car hesitates during acceleration. Or when a car stalls when trying to pull away through no fault of the driver.

 

Thats why you will see it reffered to as a symptom in many car orientated questions as it has a relation to many parts of the car systems from electronic, fueling, engine management etc. etc.

 

I hope it makes sense and don't worry about asking questions that you may think are silly, we are a helpful bunch and will always try to answer if we can. :rolleyes:
