Misfire at 2000rpm

[kmxgoon182]

Hi all, recently acquired another 182 with a long list of problems. EML Light was on showing a Df014 canister purge solenoid valve circuit. This lead me to remove the charcoal canister by following one of the guides on here. The light was cleared but returned a few miles later. Could the misfire and the canister be related or Is there something else I should be chasing down regarding the misfire ? The car runs well above 2000rpm.

Unless you have not capped the inlet vacuum take off for the carbon canister, I cannot see anything active there that would cause a misfire. at low rpm.
@bloke may have a more informed opinion.

the pipes on the upper inlet neer the throttle body have been looped together. The top of the canister solenoid is still plugged in and pipe on the right is blanked like this

The fault code is still present with this setup.

Pipes (stubs) in the plural?
It makes sense if the acoustic valve has also been removed, which explains DF308.
I junked my CC as a) it made a lot of noise &b) was full of water.
Leave the solenoid connected, junk the engine bay vacuum pipe & lt the filler neck pipe vent to air.
Never had a misfire on account of it.

Thanks I’ll double check this setup tonight and go down the usual misfire hunting route

Just look at live data, launch is good so that should show you easy enough what it is. Think it's got data recording as well?

Does it only do it under load or when you rev it?

Yeah didn’t think of live data thanks. Yeah under load its the same

Be easy then if it does it stationary.

The misfire turned out to be a crushed ht lead if anyone’s interested
