Arrrrrrrrrrrrrrrrgh!!! Guess this is what happend when you're drain bammaged. Had to be a lottery winner kind of event.
I plugin my generic OBD2 code reader, let it settle in and turn on the ignition without starting the car, comes up with Code Po105 the Map Circuit Malfunction at the same time I notice the odometer is showing a Wrench and the number 105 and say to myself, why am I using a code reader when the dash is giving me the codes?
Order a new Map Sensor and install it. Turn on the car and the dash says 113. Two days later it says 115, five days later it says 120 and I finally realize this is a count-up from the suggested service date, which was done and supposedly cleared I thought, never noticed until the Check Engine light came on.
And so I go back out with the OBD2 and the 105 code is gone ya! And now I have code Po410 Secondary Air Infection Air System Malfunction. Looked that up and found I need to check, clean or replace the Check Valves, check hoses, fix might move problem to the EGR valve.
Thanks for the coolant system info, will pick up some blue coolant before replacing the dual valves to get both center vents to blow cold.
