Hello and hope to find everyone still here and in good health. I haven't done anything else to the trailblazer since last year about this time. Wanted to update on what I am doing now since this is the only venue where people still talk about this car.
So I took out the tank today and ordered the inlet valve, new AC Delco pump and lock ring. Will install tomorrow. The inlet valve was leaking and it is visible after driving as it is damp around it. I assume that will fix the P0422 code that is probably causing a somewhat lean condition. The car is heating up again it went to 128 yesterday going up a short hill at low speed. I know that's not normal because it didn't use to do that 3 to 4 years ago. So for now I am doing the tank and getting rid of the P0422 code. I am wondering if that will make a difference.
