Help needed please

[D2 Noob]

Evening all, I have a couple of intermittent lights pop up on the dash, 1 I think is the abs sensor failing and the other on my cheapo obd says lambda. Does anyone live near Bingham I could pop over and use some of your time etc, beer tokens would obviously be given :-)

On a trailing or light throttle it feels like it's missing. It's a 2.8qs on a 52 with 70000.

Cheers Alex
