Yep the engine light was tossing map codes and one on the ambient temp. So I replaced the map and the temp as t was just a $5 sensor
The thermostat was stuck open and since I had the cooling system drained it was the perfect time to replace it.
Timing belt was due as I have 116k on the motor, the plugs were never changed, water pump and tensioner/idler were included in the kit.
serpentine was never changed.
tires are balled on the right side due to poor alignment, and the battery will not charge more then 12.15 volts on my charger. (One has one shot to start it or it will need a jump. (Oem delco battery)
Since I keep a booster pack I'm probably going to nurse the battery through for a couple weeks, however from what i see replacing it will resolve the airbag system light, since it came on the first time since I jumped it for her the first time.
however it is sure nice not having a car payment.
