1999 GMC Yukon hard start
Okay this may be odd but i have no idea what else to do. I have a 1999 GMC Yukon, after sitting all night i can go out in the morning and it’ll fire right up and runs great. If i cut it off then try to start it shortly after its very hard to start, but if i let it sit for a few hours it’ll crank up just fine. I’ve replaced all spark plugs and wires, had oil changed and pretty much a full tune up. Anyone have the same problem or and suggestions ?
