Already changed plugs, camshaft position sensor and crankshaft position sensor. Also tried swapping in my other set of coil packs. Still have rough idle and slow pedal response. Any info would be appreciated thanks 199722

Correlation code with misfire 1-4 you have a mechanical timing issue. Has the belt or chain been replaced recently?

Sounds like your timing is over advanced at idle. When youvare at higher rpms does it smooth out ? ( when the timing is supposed to be advanced. )
Id be checking base timing of belt and chain. Then move to vvt system if it checks out. .

I did the belts and underdrive pulley about 20k miles ago. Did replace the tensioner for the accessory belt somewhat recently maybe a few thousand ago. Last time the code said advanced timing and it was the camshaft position sensor, thought maybe it went out quickly again but a no go. It does smooth out while driving at higher rpms but it’s a lot slower getting up to speed
