RB 182
few days ago now my emissions light came up on my dashboard and was gettin 29-30mpg so gathered it was a problem with the lambda sensor, rang renault n they wanted 59quid for a diagnostic so then rang fred at yozzasport and he said he'd do it for free so was all set to go there next week but got in car last night and the light gone off after 5 days of it being on!! so i reset the comp and im now gettin 36mpg again. so now im confused what to do. is it ok again or not? just a loose connection u reckon?
