Poor idle.

[greavey]

As per title. I have cleaned throttle body, iscv, flywheel sensor, new air filter, adjusted tappets, replaced manofold (was cracked but did not cur problem), cleaned plugs, replaced radiator (was leaking but problem no better since.


Any help as to why i have a poor idle speed would be gratefully recieved. it sits at about 700 rpm. I will upload an image later if anyone is interested to see where the needle sits. its a scenic 1.6 8v

It could be a pencil coil? if they are fitted to your engine? but your model could just have a single coil but if it is the case it has single pencil coil packs per plug my guess would be its a faulty pencil coil,Gnash

checked the MAP sensor pipe for splits?

Checked map hose = no cracks. No pecil coils just single block. No mayonaise in oil filler or water bottle

when you tap the icv do the revs change? does the engine every stall?
