I have a 1995 4 runner and when i started it up the other morning it went through it's normal routine of the high idle and then after a minute or so the idle dropped down to normal and then all of a sudden i heard a clanging noise and then the motor shut off. I then started the motor again and this time it was running very rought and sounded like it wanted to shut off. I tried pressing the gas pedal to rev the motor up to keep it from shutting down but it had no effect, the motor continued to run rough. I then put it in gear to try and drivr the vehicle but it would not power up to move the vehicle. I do not see any fliuds leaking all over the ground or any other visible damage and with that said i was wondering if anyone knew where i need to start so i can get this truck moving again and continue my journey of 300,000 miles. It currently has 239,220 miles on it.
