This is on your '91 318? Has it actually got a cam position sensor?
Thought that only came in with VANOS.

Crank position sensors do go 'iffy' - had one on my E39, but it threw up a
code. They used screened cable, so it's quite likely a fault there could
introduce spurious triggering.

A while back I was searching out a problem where my car would not turn
above ~1500RPM. I finally got sick of trying parts (fuel pump, filter, air
meter) so I took it to the most recommended shop around. They had it for
over a month trying to track down the issue. It was setting a cam sensor
code, but they replaced it with one known working to no avail. Upon request
I tracked down a used computer on ebay, thank you to all who helped, but
that also made no difference. Turns out that a new scope they had purchased
finally revealed a lot of noise from the crank position sensor. Replaced
that and ~$600 lighter I'm back on the road. I had never heard of a crank
sensor going partially bad like that, only quitting completely. Anyway,
thanks to all who offered thoughts on my issue.
