Hey, so I'm new here but I figured this is the best place to ask this question. So I was driving my car today and it started acting funny. The first sign was as I made a u turn and I got on the gas a little it started fluctuating between 500 and 2000rpm so I let off the gas and fluctuation stopped. I was able to drive about three miles home smoothly and parked. Then about ten minutes later I left again and drove a block and it shut off as I left a stop light. I figured it was just an anomaly and started the car and kept going uphill. But then it happened again it would roll at idle and as soon as I gave it a little gas it shut off. Then I started again to take it home and it cut off while I was turning. It is very smooth when it shuts off and you can barely hear it when it happens. It still has battery power when it shuts off though. I have checked my battery and terminals and wires, all of my coils are plugged in, and there aren't any obviously visual problems under the hood. I have an automatic transmission that was rebuilt about 1500 miles ago. any ideas?
