I would guess coil pack. I used to use a spray bottle on the wires and around the pack to see where it would arc at.

Your first code could also be the cause of the Misfires since if the EVAP system doesn't function properly you could run into the misfire issues.

16824/P0440/001088 - EVAP Emission Control Sys: Malfunction

Possible Symptoms
Malfunction Indicator Light (MIL) active

Possible Causes
Evaporative Emission (EVAP) System leaking
Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80) faulty
Evaporative Emission (EVAP) Canister Purge Solenoid Valve (N115) faulty

Possible Solutions
Check Evaporative Emission (EVAP) System Sealing
Check Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80)
Check Evaporative Emission (EVAP) Canister Purge Solenoid Valve (N115)

I don't see how the evap valve could cause a misfire or even the opposite. I think you may have 2 issues.

Do you have vag-com? If you do you can run output diagnostic test mode with the valve removed (but plugged in) and when you test the purge valve you should be able to tell if it is plugged or stuck by blowing through it. It should open and close which stops the air. You could also test it by setting that part of the readiness code.

Thank I will try suggestions. I replaced the coil pack and still having problem. I get a strong fuel smell but im thinking that is from 3 and 4 misfiring. I have tried to run the vacuum lines but if anyone has other suggestions, I am open to them.

I will be running through the above posted suggestions today

how can this be done? instructions? where is valve located? Thanks...

Well with a vag-com tool with output diagnostic test mode you could check it. I suppose you could pull it out, make a jumper and try to see I you can open or close it with battery power, but that is could be risky I it requires < 12 volts. I have a turbo but will try to look in my Bentley for location.

I am going to guess it near the evap canister in the rear. The older volkswagens had them in the engine compartment, but honestly I can't find the location in my Bentley. I went to school on these before they came out and have a tech training book, but it is buried in my garage. I did a search and lot of threads came up on it. You could also do a new post in the 2.0 section asking the location of the evap purge valve. Also called the N80 valve in Bentley.

sorry for the delay. i have had to just park the bug and wait until i have time. I did use the vag-com to check the valve and it seems ok. I cleared the codes and drove the car around the block. Still getting the same misfire codes. Kinda stumped about where to go next. Could this be an injector issue? Open to any ideas.

What plugs and wires did you install? What gap did you set the plugs to?

So you swapped out the Coil pack. How about the spark plug wires and spark plugs? Also when you replaced the plugs did you gap them properly? Some of those plugs from the store have a HUGE gap from the factory and need to be properly gapped or you will have misfires all day long.
Hope you find your problem soon.

You can put some SEAFOAM in your gas tank the next time you fill up to clean the injectors but I seriously doubt they are the reason for your misfires.

thanks for all the help

I have had to park the bug for the last few months. Been a real pain sharing my 91 pickup with a family of four :|

I am jumping back into for the new year. I have been trying all the suggestions. I changed out the fuel filter today... just for kicks. no difference though.

Ill keep everyone posted but keep the ideas coming.

Check and make sure the plug wires are in the correct location. I changed my coil pack out on my old NB because of misfires. And I accidentally put the wires back on incorrectly and caused misfires again.
