Suzuki: 94 sidekick, suzuki experience, throttle position

Question
will cut out at 2000 rpms anyother rpm runs fine help

Answer
Experiment a little and see if throttle position in a specific gear makes a difference.
Unfortunately, almost all my Suzuki experience is with early (87) carbureted cars, and it is a little harder to determine whether you're losing spark or fuel on a fuel injected vehicle.  If it does it in neutral and doesn't have to be driven it will help lots.
See what you can come back with for circumstances.
