Newbie With Yaris Problems

[New to DIY J]

I have a 2002 yaris, when driven around or below 2000 revs the car judders and sounds to misfire plus when idle it sound rough, i've replaced the coils/spark plugs/lambda sensor/canister purge valve (vacuum valve) and had the air flow sensor check (which works OK) but no joy, it's been mentioned that it could be the throttle body or the fuel injectors.

Can anyone help?

Thanks J
