Hi
Drove car home from work yesterday all fine. This morning started first time with no problems but it won't rev over 1000. Did'nt notice any lights on dash. Could it be the maf ? Got RAC home start so my call them out when i get back home to see if there are any fault codes

Could be lots of things, but the throttle body stuck almost closed would be my first check to make, as it's used at engine shutdown when it may have failed. A MAF won't fail after shutdown, unless you've had rodents chewing wires, which happens around me on occasion. Hyundai Ioniq 5 Ultimate. The family car.
2009 Rimini Red SE TD4. Gone.
2006 Tonga Green i6 HSE. Gone.
Audi A5 convertible, my daily driver.
1972 Hillman Avenger GT, the project.

Yes that would expain why it was ok yesterday but not today, will have a look later

Got a new throttle body from Eurocarparts and noticed that on the new one the valve was open. When I disconnected the turbo hose I could feel that the valve was closed. Removed old one and valve was almost shut. New one fitted and engine runs as it should. Opened up the old one and found some of the gear teeth were damaged and holding valve shut
