I don't need to drive the car frequently but yesterday was the last straw since I couldn't get it to go over 50mph. I went to AutoZone (thanks to my daughter's suggestion) and had a guy use the test gizmo and it came up with P0412-Secondary Air Injection Valve Circuit. And P0135 & P0155 Heater Circuit (Bank 1, Sensor 1 & Bank 2 Sensor 1).
I've installed the two new sensors and the light doesn't go out. I checked out a place saying that doesn't always mean it hasn't been fixed. I've tried the easiest one which was to start engine three times. No change.
I'd like to get the rear situation fixed before lowering the car, but when I do I'll take it for a drive. Another fix was to remove one of the cables to the battery but then it needs to start from ground zero and takes time to get back in the groove, so to speak.
Or...should I also get the P0412-Secondary Air Injection Valve Circuit in any event? It appears as if a bunch of aluminum needs to be removed to get to it.
Comments?
The air pump does not affect the performance unless there is a leak in the hoses, all the parts are on the front of the engine.
Sounds like a vacuum leak in the engine somewhere.
