strange L-Jet Spider throttle trouble
Most likely the bell crank under the intake plenum is
partially frozen, and is binding intermittently, possibly
in relation to temperature.
Remove the bell crank from under the plenum, take it apart,
clean and lubricate it and it should fix the problem.
You can remove the bell crank without removing the plenum,
you will require some very long extensions, universal
sockets and/or flexi-sockets, and a lot of patience but it
can be done.
HTH,
Jeff

throttle trouble
Hi Group:
I'm having a strange problem with the feel of the throttle
pedal on my '87 Spider. With no prior warning, the
throttle pedal will become very firm. It might take 20
minutes of driving or just a few, and then it might come
and go several times in the space of an hour's drive. I
can't think of anything I'm doing that induces the feeling,
and I've only driven at a sedate pace while this has been
going on. It doesn't feel as though the linkage is
seizing, because the pedal will return quickly when
released, and the engine rev's will drop normally. When
it's happening, it feels like the return spring has just
become much stronger, which makes it difficult to modulate
the throttle. It becomes almost either full-on or
full-off. So, who's got a guess? Why can't both my
Spider's have Spica FI?
Regards,
Dean Lutz, FL '74 & '87 Spider Veloce's
Good advice, and one more place to look is/are the heim ( sp? )
joints ( ball/socket ) of the pedal linkage - they get flat spots
after a long time ( shorter time if one never greases them ).
