I am having problems with a 93 gran prix 3.1, It will start but after 5 minutes it will stall and wont start until it cools down. It don't seem to have spark when it stalls. At first it seemed like it wasn't getting gas because it would start with a shot of ether. I changed the fuel filter. my friend drove through some water the day it started acting up but don't know if its related or not. Any help would be appreciated. Also the check engine light is not on and its not throwing any codes.
