Hi im new to the forums but I have a 1991 Camaro RS it has 200,000 miles but has worked perfectly up until 2 weeks ago one of the hose connections broke off on the heater valve so I just bought a new heater valve and put it on. Then all of a sudden it was running very hot and sometimes when you start it it would just die right away. I replaced the thermostat and that has made it stay plenty cool (has never gone over 220) but I am having worse starting problems then ever. Any ideas?

 

Good thing theres anyone here that knows a lot about camaros
