ok so it does some funny stuff. initially , i'd guess thatthere is a
defective rack. a bad power rack attimes gets stiff like it looses it's
power assist. usually when cold or in extreme ends of it's operation like
paralell parking. but! in the age of computerised automobiles there are
sensors for evrything! now there are sensors that increase the engine speed
when a power steering rack requires aditional boost from the pump to
compensate for the drag of the pump working. in adition there are also
sensors that monitor the airconditioning compressor and increase engine
speed when it is engauged to compensate for the drag of the compressor's
doing it's job. now these are generalised statements about these 2 systems.
but my suspicions are the 2 systems sensors are not working together and the
added drag on the engine is not being electronically compensated for
therefore causing the hard steering and belt squeeling. somewhere a sensor
that monitors a change in pressure either in the airconditioning or power
steering is not properly reporting a system status to the computer and the
engine management system is not compensating for that systems demands.
sort of like a lean condition created by a vaccume leak. so you richen up
the fuel delivery and all is well with the world.....then the vaccume leak
gets fixed and it runs rich.....because the the problem was not the mixture
of the carb but an air leak somewhere else.
so, the culprit is not the belt or it's tension. now it could be a
defective driven component but i think it's in the electronics sensing what
is being operated and when . due to the fact that most power steering
pumps and airconditioning compressors either function (properly or noisy) or
they sieze solid. i'm banking on modern technology's failure in this one!
could be a bad engine management computer too? not processing sensor's
input. needs to be hooked up to a diagnostic computer and have it's little
elexctronic brain picked to see what's going on ...or not going on?
chuck.
hey ! i've been thrown out of classier places than this before!
lol!......c :)
