No it will not cause evep odes or jerking under acceleration. Does your check engine light ever flash? Has anything been replaced? Thanks.

i have yet to find the fuse for the evap controls
Expert:  Dan replied 1 month ago.

P0466 is related to purge valve which can cause performance issues so I'd start by replacing that and if jerking is still happening then I'd replace spark plugs and test spark strength to see if you have a failing coil. Let me know if you have more questions, thanks.

Well do it all started at the same time but but prob. Want hurt to change the plugs lol thanks

If light came on at same time as problem then purge valve is likely the cause. Let me know how it turns out or if you run into more questions. Thanks again and have a good night.
