Hi again! Need some help, so i have a 1.0 yaris S on a V reg. Which starts and drives, however if you floor it in neutral it sounds really throaty and sloe to rev? Iv checked standard stuff like the air filter and general maintenance stuff? Any ideas or fixes would be great! Thanks in advance

Plugs? when replaced?

Any misfires? Coil packs can fail.

Check ALL piping for splits.

MAF sensor dirty (my first port of call...( can be cleaned.. with GREAT CARE).. or failed.

Blocked catalyst /exhaust.

New plugs if not changed in last 20k miles and MAF sensor first..
