Hi there guys......my friends car failed its MOT on emissions and he has a retest next week. The mechanic who did the test reckoned if i took the fuel head (i think) off and clean it. It would help. Also to put something in the engine to help clean it out (he didn't suggest what).
The car has been kept in storage for 6 months and has hardly been driven since. Would giving it a good run help at all?
Any other suggestions?
