Now you say that, the day I got my car the exhaust emission light came on i had it scan and it also showed two faults for the MAF sensor, we didn't know how long they'd been on there and i thought the car was fine so we left it at that, could this be because it was dirty?
I've found the electronic cleaner in halfords online, if I remove the sensor and spray it should this solve the problem, that's if it's dirty and not broken?
