My engine management light came on after my 2002 bug eye wry stood for a bit the battery was flat got it reset and its come back on it's saying it's running lean on bank 1
The car has a dump valve prodrive exhaust with a noisy back box and an eBay special induction kit
I was advised to change the plugs and coil packs but if it's running lean is that the right advice any help would be great
Cheers
