Lumpy idle when warm!!

[Metroracer1985]

Hi guys got a problem with my saxo, when the engine is warm i get a lumpy idle, It sometimes cuts out also,
I've changed the ICV, Spark plugs, Coil pack and coolant temp sensor but the problem is still there,
The only other thing i think could be causing it is the MAP sensor.

Any help would be appreciated.

Signs point to a coil pack breaking down,i had the same problem.

Can't be the coilpack as its had a brand new one fitted the other day.

Map sensor?

[axsaxoman]

too many possibliites to be accurate with a cause -need live dat from ecu to see more -could be lambda ,lots of things get it diagnosed

Give the ICV a clean with some carb spray.

Could be another possibility.

Doesn't mean a thing could still be faulty.:drink:

New plugs gapped properly?

[doctoromeo]

check for air leaks ,loose inlet bolts ,pipes fallen off?
wiggle the wires on the various connectors ie ,coil plug coolant plug etc to see if you can stop the misfire whilst you move the wires.

I think ive figured out what was causing it, it was the induction kit, i removed it and fitted the standard air box and the rough idle has gone, hopefully it doesn't come back.
