4.3 won't stay running
I'm working on a 94 c1500 with a 4.3 it starts right up and will idle for about 15 seconds then surge a couple of times and die. If I unplug the map sensor it idles fine and doesn't die. I've replaced the map sensor and it didn't change anything I have checked for vacuum leaks, wiring problems and all connections. If anyone has any ideas I would appreciate it. Thanks in advance.
