I have 1193 olds Cutlass S ... been running a long time(up to 203,000
miles).  Well about at 190k I had trouble starting the car ... it would
crank but not go ... come to find out, bad coil.  Well a week later the
same thing ... but it would eventually start(poor starter), it started
more often after the car had been warmed up ... took it to the same shop,
coil is fine ... Well they thought it was a O2 sensor, but i was
consipicous ... i called a show called car talk and they told me it was a
crank saft sensor, but i told them it checked ... they told me sometimes
the check doesnt always work ... well i ended up needing the car bad so i
put in a new starter and wires and they relaced the O2 sensor and crank
sensor ... cannot really tell you what it was, but my father and i swear
by it ... it was the crank sensor ... hope it helps (you just might want
to dump the thing, but of course my car runs great ... i dont have to add
any oil ... still runs strong too ... of course, it has always been in the
family ... remember a car is like a chick, take care of it and it takes
care of you)
