In an attempt to trouble shoot my car, I hooked up my pressure gauge and it measured 30
PSI. When doing that, I bumped the wire for the head temperature sensor and the car
started to die. I moved the wire again and it ran better. Bump wire = die, move back =
smooth idle. This happened with a regularity that I am not familiar with when trouble
shooting my car, perhaps it is the problem. (Most problems I have been having are very
intermittent.)
Looking closely, the wire from the harness is coming loose from the spade(?) connector
inside a plastic housing to the temperature sensor. The connection spot is just behind
the generator if that helps place it visually.
Thanks Jim A. for hinting that the problem had to do with A) warming up and B) the temp.
sensor. And I suppose my clumsiness is helpful for once.
Now to figure out how to best reconnect the two wires so I can test in the future if
needed.
Anyway, thanks for the hints on the list.
