Good day,
My 740T has started running awful.
Car is 1990 8 valve 740 turbo with 4 speed/overdrive (M46)
transmission.
It is rather cold here.
Car was warmed up and driving normally. Check engine light came on and
it driveability went to crap.
Wife had it so I had to go pick it up as she was afraid to go the last
few miles to home.
It starts and idles OK.
Push accelerator and RPM surges and drops repeatedly and there is no
power to speak of.
I managed to get it rolling and up-shift to keep the RPM low and I was
able to limp home. Good thing there were some downward slopes.
I am suspecting:
Failed AMM (electrical connection, dead AMM)
A clog in airstream
Dirty throttle body
Thoughts?
Side note- amazing that it will chug along in OD at 1000 RPM once it
is moving.
TIA
