Hey, i have a problem with my senic, i have replaced all 4 coils and the o2 sensor and the cat, but still the fuel ems light has come on after about 400 miles . can anyone help with out me spending alot more money.
hi m8 and welcom to the forum, the only way to solve this without changing the whole car in the process lol is to have the fault codes read.
this will tell you were the fault lies and cuts out the guess work and saves the wallet
most independent garages now have suitable diagnostic software and are reasonable on the price aswell.
