Yesterday while driving my 99 Rav4, the gas pedal became unresponsive and RPM immediately dropped from 3000 RPM to 750 (typical idle status) RPM ... I pulled over and brought the vehicle to a stop and then all of the warning lights came on. During this time everything else seemed to be working fine, the brakes, engine, all the electrical stuff was working normally, it was just that the gas pedal was completely dead. I turned off the vehicle and after a few seconds restarted it and it was running normally again. From there I brought it in to the dealership and they found no problems with it (and there was no code stored). They basically said they had never heard of this problem happening before and had no idea what the problem was.
I was hoping someone out here may have experienced this issue before.
A little background, a few weeks ago I was having an intermittant problem getting the car started. It took multiple towings to the dealership but they were finally able to replicate the problem and found that the fuel pump relay was faulty. That was replaced and since then the vehicle has had no issues starting.
