It's on again...

Richard,

2 suggestions:

- Buy an OBDII Bluetooth plugin (£5 or less) and use a laptop to load the software that is almost always supplied with the plugin, and then use one of the programmes to just monitor the lambda voltages. Or just find a friend with an Android or iPhone then use a suitable app (Torque Pro or similar) to monitor the voltage traces.

- Use a multimeter and back-probe the plugs of the lambda sensors at the top of the engine to again monitor the voltages. Easy to do with the car sitting still, but not easy to do with the car running unless you've got long leads, some tape and more than one multimeter!

Good luck

Paul
