My 4200 Cambio Corsa won't idle below 1800 RPM.

Help guys what a day almost undriveable this weekend no management light on and no fault codes in ecu.
Had a good look around inlet manifold and can't find any air leaks.
After nearly 7,000 miles can't believe what she is doing but you can imagine what its like trying to pull away or reverse her.
Anyone got any thoughts?
Phil.

Maf sensor?

Little update have had all the induction side off today and found the throttle housing to be near spotless had fun and games getting the airflow sensor out with the anti tamper screws rusted but got them out and gave a good clean with forte air intake cleaner put back together with new screws and let idle for a good 20 mins still around 1400 rpm but on getting home after 10 miles she seams to be back to her self.
Not sure if mine might be going into the menopause.
Do i treat her gentle or give her a good thrashing?

Throttle pedal pot. Give the gas pedal a wiggle by hand to see if you can get the idle down.

 

[philw696]

Cheers for that Matt will have a look at that too.

Update guys its the airflow sensor that was playing up although still in its parameters so not putting the management light on.
Drove the car with it disconnected and it drove ok so new one ordered so she will be back on the road for the weekend.
