The plot thickens ...
Hello Everyone ...
I promised myself last week that over this past weekend I would locate a fuel pressure accumulator and get it on order. I didn't do it.
About midweek we had a change of weather that began with a day of severe rain followed by cold/chilly temps and higher humidity. Since I use this car every day, I was out in that rain. The first thing I noticed is that it started up like a new car in the rain. All day it started great and idled nice and smooth. It was enough to make a fellow smile thinking he has a miricle car that can heal itself. After the rain went away, temps of 15+ degrees lower than the preceeding week have been in effect along with higher humidity. The car has responded very well. It starts well and idles smoothly, even when in gear while sitting at a traffic light. I believe that up shifting itself is smoother also. And, to get this wonderful effect, I did absolutely nothing.
If the car had a carburator, I would begin by thinking that it was running rich in the hot, thin air and now, with lower temps and more humidity, it is leaning itself out and running better. I know nothing at all about the Bosch fuel injection in the car or how it works. I will read up on it this week.
Can it be that the two situations are somehow related? How could parking with the nose down make it leaner, or at least have the same effect, so it would run more smoothly then and now in the cold? Or, how could parking it with the nose up have the exact opposite effect of droping temps and higher humidity? Is there any connection between the result of parking nose down and the result of colder, more humid temps?
Or, as always is the possibility, do I have two different conditions existing here that need to be treated seperately?
As always, any input from you will be deeply appreciated.
