Answers:    Get some Cataclean (or any fuel system cleaner) and try that within your fuel the next time you stuff up or get some super unleaded close to Shell Optimax, BP Ultimate (no supermarket fuel) etc and give your coup¨¦ a really good blast on the motorway for around partly an hour in a low gear, fourth or even third at a high-ranking speed (70mph). You may have a nouns of carbon build up on your engine making burn ineffecently. This is highly probable if your car with the sole purpose does short trips or town driving. Once you have done this, retest. This should oblige!
