I just replaced the spark plugs on my 2003 saturn vue 2.2L engine and now every time I let off the gas my car stalls. I used what was recommended at the parts store... Bosch +4, supposedly like the original plugs. What could be wrong?

The P0304 indicates the #4 cylinder is misfiring. The flashing light means the cylinder is not firing at all...It could be several things causeing it, coil, wires, plug, injector or vacuum leak. Do not drive your vehicle until you have this repaired, as it will lead to further more costly problems. Good luck, i hope this helps.
there's no adjustment, unless you have a scan tool then you can see it. Information not supplied by the manufacturer.
I have seen the ignition control module going bad all the times on these
The electronic ignition system on the 3.0L dual overhead cam (DOHC) engine provides spark energy to ignite the air/fuel mixture necessary for combustion. The Engine Control Module(ECM) controls spark under all engine-running conditions. The system components include: the ECM, two Electronic Ignition (EI) modules each which house three primary and three secondary coils, spark plug boots, spark plugs, Camshaft Position (CMP) sensor, knock sensor and associated wiring

Did you use the recommended plugs or did you use a new style like E-3 or Bosch +4 or something similar. Sometimes using a plug other than the original type can cause problems. Check and make sure all the wires or plug connections to the plugs are secure. Check to see if a spark plug has a cracked insulator. If you used antiseize on the threads make sure none of it got on the spark plug electrode or it will missfire.
