Please can someone give me some advice? I'll try and be as clear as possible...
Disconnected air hose from airbox to AFM earlier this afternoon to get better access to the airbox (replaced standard air filter for Courtenay one). When replacing the hose, I broke one of the jubilee clips (at the AFM end) and drove to a motor factors to get a new clip. On the way to the motor factors, the car suddenly felt like it hit the rev limiter at 4000rpm and the engine management light came on in addition to the traction control light.
When the car was stopped I did a pedal test and the fault code p0100 came up. Bought a replacement jubilee clip and reattached it and now the engine management light is off, but the emissions light is on instead. The traction control light is still on.
Please can anyone advise some diagnostics I might be able to do or suggest what is happening here? I know the fault code refers to the AFM and I'm worried I've damaged it by running the engine without the jubilee clip clamping the hose securely to it (although it didn't actually come away).
Car is a 2003 Astra Cabriolet Turbo - Z20LET engine.
