My car is hissing very loudly and won't pick up speed past 3000 rpm. We have changed the spark plugs and leads. We also changed the air filter and used a carb spray.
I have identified that it may be a vacuum leak as we have tried all other options.
Please help. I can't afford to take it to a garage. Helpless female : )
