My 2001 civic intermittently stops accelerating and then kicks back into gear while driving. It's not a stall, because the car doesn't completely lose power (the radio, a/c, etc. keep working), but the car stops moving. It almost feels like trying to drive with something stuck under the wheels
-- I press on the accelerator pedal but the car doesn't move. No indicator lights appear, nor are any problems coming up in computer diagnostics. The service people thought the problem was in the fuel supply and have tried a couple of things, including replacing the fuel pump, but there has been no change. They've basically admitted that they have no idea what the problem is, but the car isn't safe to drive. It only has 49,000 miles on it.
Does anyone have any ideas at all?
