Got myself a 1999 4.0S with a GEMS engine.
120K on the clock.
PO told me the following:
*New Arnott airbags
*Hood (bonnet), grille and radiator replaced due to accident
(still checking for hair and brain bits)
*GG AT2 Tires with half tread left
*K&N air filter
2001 P38 4.0S RPM drops to 2000 when first started in the morning
2001 P38 4.0s RPM drops to 2000 when first started in the morning but stabilizes after 10 minutes. Does anyone know the cause and solution. I also noticed that when the RPM has stabilized and you turn the AC on it drops and stays...
I'm getting the fault code P1193 - Oxygen Sensor Heater Circuit Open Downstream.
I take it this is the rear O2 sensor, any Idea how to tell which side is faulty?
I found these sensors and according to the site, the rear ones are different from the front. Checked the same for the 1998 model...
