Been having problems with my 93' Camry overheating. I can drive the car for about 15 minutes before it starts shutting down and not wanting to start again. It only dies when the rpms are really low though, for instance when i stop at a light or to turn, and pressing the gas stops it from dying.

The car then wont start for 10-15 minutes, and i have to hold the gas down for it to catch and go again.

Wondering if maybe its the fuel pump or if its the distributor. Anything i can do at home to make it work better/longer? Is it worth taking to the mechanics if i'm not willing to invest alot?
