Cold start EML issue

Messages

Hi guys,

Right on a morning or if the cars been sat long enough for it to cool down i have a slight problem, after half a mile or so its bogging down been hesitant for 30 seconds and eml light pops up. If you give it a bit of throttle bogging stops but eml still comes up, if i let it warm up for five mins you can still hear the engine chugging for 30 sec's after about a minute of warming but the eml doesn't come on. It has 4-2-1 and exhaust (decat) k100 tegiwa intake, iridium plugs any idea what this is? and also as soon as eml comes up if you flick the engine off and back on it disappears and its fine and it never does it when its warm help please??? :confused:
 
Idle Control Valve (ICV) could be the culprit here.

Is the car bogging down only when it's at idle ??

Like you say when you give it some gas it smooths out again, is it alright when its under drive ??

Not sure if the EML is triggered from a misreading ICV on an EP3 though :? .

Get some carb cleaner and give it a clean.
