My nephew has 2006 a4 3.2l. Was running in autocross and car died at finish line. Now can only get it to run extremely rough for 5 seconds and then it dies. Will not fire at all unless it sits for about an hr. Codes coming up are p0304,p0305,p0306. Where should I start? Trying to help him so he doesn't have to spend a bunch of $.
Thanks,

What are the symptoms of the P0304 code?

• Engine running poorly or having trouble staying running
• Check Engine Light present
• Misfires
• Lack of engine power
• Decreased fuel mileage

How does a mechanic diagnose the P0304 code?

• The mechanic will begin by hooking up a scan tool to the DLC port to determine which codes are present.
• Freeze frame data will be associated with every code found and should be noted for use on the test drive.
• The codes will now be cleared and a road test performed under similar conditions to the freeze frame data from earlier.
• Next, a visual inspection will be performed looking for damaged wires, worn or broken components, or visible leaks.
• Next, the scan tool will be used to monitor the misfire counter for cylinder 4.
• Then, the scan tool will be used to look at the long-term fuel trims to see if fuel issues are present and the intake air pressure checked to see if vacuum leaks are present.

Check the harness for the coils. One whole side of the motor has spark issues. I highly doubt that three coils or three plugs died at the same exact time.
