I have a 95 tahoe engine in my 88 k1500 and i cant seem to keep it running consistently. it will start with starting fluid and will stay running all day, it stalls sometime when its in park but will start right up.

If i try to start it cold the next day it will start with starting fluid but it wont stay running and if i wait a few days the same thing will happen where it seems like its running pretty well for a day and the next day it wont.

Anyone who could point me in a direction would be much appreciated.

Thanks!
