1. Clean out the throttle body with carb cleaner.
2. Clean out the MAF sensor with electric contact cleaner, and use a cotton ear bud for the delicate sensor bit inside.
3. Remove both battery terminals from the battery (the positive and negative cables basically), and get a jump lead, and connect the positive cable to negative cable and leave that overnight. It basically's ment to reset the ECU. Now before you do this, I'm not 100% sure if this will also reset the immobiliser (and if it does, then it means you need to recode / pair up your keys again) So you might want to check this before attempting this last step
