What is Sea Foam,and why would you add it?
Nothing I see but the spark plugs,addresses your issues.
Have you looked at the TPS Sensor,with a scanner?
Have you looked at the Ignition with a Scope
Checked MAF Sensor data and cleaned it?
Is the Egr Valve working correctly?
Have you checked fuel pressure?
Are the O2 Sensors,15 years old?
Is the Converter,15 years old and blocked?

2004 CROSSFIRE 52,000 MILES, CAR STALL AT IDLE, HESITATES WHEN PUSHING GAS PEDAL DIED TWICE WHILE IDLING. INJECTORS? FUEL FILTER? AIR FILTER?


This happened to me at 53,000 miles. Its your air flow sensor. This runs at about $200 for the part plus labor.

It may be throttle position sensor or camshaft sensor. Most likely the throttle sensor.
