car not pulling like it should/usually does?

[nickshally]

My clio 172 is not pulling as strong as it usually does and is also judering/misfiring maybe
Only started just now.
Any ideas guys?

Could be anything really chap, something mechanical but most likely electrical.

Honestly, I'd advise a proper data logging session on a proper diagnostic rig rather than a code reading session to find out what's actually wrong.

Am gonna check filter and few things tomorrow and see how it goes
As it started today badly but have had a few judders over the past few weeks
