hi corsa 1.2 8valve p reg 125000 miles on the clock i have a problem when i start my corsa up in a morning it misfires until i go to drive of then when the engines warmed up its fine for the rest of the day anyone got any ideas please and there is mayo like stuff under the oil cap and its starting to get in with the dipstick there no eml on or any other warning light but like i say runs fine once its warmed up. thanks

Buy some Carb cleaner and spray the AFM. (Airflowmeter) if still doing the same also clean the ICV (Idle Control Valve)

This is a comment fault on majority of vauxhalls.

Where is the AFM located?

ok thanks i will try that i have found out what the mayo like stuff is had my lasses mate who works on cars have a look water pumps faulty and the head gasket is leaking so going to get that done when the moneys sorted and after i have got that fixed i am going to buy a service kit and give it a service then while i am on with that i will also have a go at cleaning what you are on about see if that helps cheers for that mate .

Where your airbox is follow it back towards the CARB you will find a PLUG connected to the hose before the CARB
what the elecrical plug is connected to is the AFM (airflowmeter)
Isnt my car BUT thought ide show you where it is on an image...



PS:
once you take it of to clean place back ON and dont connect the Airbox straight away,
connect it all back together all but the hose with the airbox and gently spray little bursts at a time only need 3 little
short bursts as doing this will also clean towards the carb, you will see a difference IN idle while spraying
but will drop back down once Carb cleaner is dry usually takes about 1-2mins.
turn off the car and then reconnect the airbox with hose onto the other part of AFM...



Hope it helps good luck

ok mate thank you for that
