hi... I've bought a cheater and waiting for it in the post, my car seems to drive ok, mpg is crap tho, and my engine management light is constantly on and when i get it plugged up its alway an egg fault... I've got a blanking plate ready so all been well it should solve... anyone got any input into what I'm going to do? also i have an oil leak on the left side of my engine (astra coupe z22se) same side as alternator... any ides were it will be coming from???
Also once i fit the egg cheater will my engine light go off? or will it need turning off??
many thanks.
