Greetings,

The problem with my daughters car turned out to be a faulty hall

effect switch. The symptoms: The car would start and run fine. when i raised the engine rpms it would begin to miss. After the car got nice and warm it started to sputter and it would eventually die. once it cooled off

it would start and run. Until it got nice and warm and...

Now I remember that I didnt have the engine miss at first. I caused

the miss. What did I do. Well, I put a borg warner ignition coil on it.

I got it from pepboys!. Replacing it with a volvo coil made the miss go away! Draw your own conclusions.

In trying to solve the stalling problem I was watching the ignition

with my timing light. The ignition appeared strong. I did notice this:

as the engine ran worse and worse the timing retarded, off the scale.

Replacing the hall effect switch solved the problem.

Id appreciate very much if someone could explain, in laymans terms,

how that switch failed . My engine was retarded to death? Yuk!

I also found a psychotic temp sensor.

Also my hats off to the guys and gals at Sacramento Volvo service(svs) in Sacramento, Ca. Once again they saved the day. Friendly, courteous, and expert service. They even washed and vacuumed the car!

Also thanks to all the guys and gals on this board who provided input. Thanks for taking the time.
