Hey guys,
I have a 2.3 N/A with a 4spd automatic. It's also a duraspark motor.
I seem to have a choking start up. It's very quick to come and dissipate. It's only within the first 1-2 seconds of start up, but I know it's not a proper firing.
So far I've replaced:
· Replace Both Coil Packs
· Replace Spark Plug Wires
· Replace Spark Plugs
· Replace Thermostat
· Replace Timing Belt
· Replace Crank Position Sensor
· Replace Crank Hub
· Replace Air Filter
· Change Oil & Filter
· Replace Valve Cover Gasket
· Replace Upper Intake Gasket
I'm not sure what else to replace. It does smell like it's firing really rich for a few minutes. Could the o2 sensor be going bad? What else should I look into replacing? I checked the ICM (loaded it 30 times back to back to make sure it wouldn't fail).
Thanks guys!
