03 Zo6 p0300 Miss on cyl 7 & 8 replaced coils plugs still have misfire on 7 & 8

Code 300 is a random miss rather than a specific cylinder.
If you have a loss of power on one or more cylinders, it could be a fuel injector or mechanical problem in addition to spark.

03 mitsubishi eclipse 2.4 4 cyl miss fire on 2 and 4 cyl going by the firing order they are not getting fuel the car was running fine shut it off went back 2 hours later and that's when it started...

If you know for a fact the injectors are not opening, you would need to check for voltage and a ground signal from the computer. The computer grounds the injectors to open them based on the crank and cam sensors.

Switch spark plugs, ignition coils and fuel injectors from cyl 1 to 3.
See if misfire goes to cyl. 3. If that happens replace the damaged part.
If is still on cyl. 1 check the compression of the cyl. 1.
If that's ok see if the air mass sensor is working fine.
Also check if there is oil in the plug of the lambda sensor.

CEL light flashing-shuddering when idle. 03 passat 1.8 Turbo. Thinking its an air leak somewhere? Can hear air but can't figure out where its coming from...

A flashing cel indicates misfiring. A common problem is a bad ignition coil. The easiest route for diagnosis is the check the trouble codes(autozone and some other parts stores will scan for free, or an OBDII code reader is not too expensive to buy). The code should tell you which cylinder is misfiring(PO301 means cyl #1, 302 cyl #2, etc). Once you know which it is, swap the ignition coils around. If you have a #1 misfire, swap coils 1 and 4, clear the codes, then check it again. If the misfire moves, you know you've got a bad coil. If the misfire is air or fuel related, as with an intake leak, other codes should come up as well as the misfire.
