my rondo was dead,I got a boost and it started,but when I gave it gas it wouldn't go above 1500 rpm. I shut it down restarted and everything came back to normal,anyone experienced this,

Hello, If the battery was drained because of something being left on, you are fine. If the battery was drained for some unexplained reason, have a starting and charging system test completed. The 1500 RPM limit is part of limp mode, and the battery charge needed to reach a certain point before restating the vehicle would allow normal operation.
