Good Morning! I've seen a lot of posts on this topic but haven't found where it's been solved just yet.
Scenarios
Truck fires up just fine after sitting overnight
Truck fires up just fine after being off for 5 minutes or so
After a few hours I need to hold WOT to get her to fire up
Truck always runs rich
Brand new Delphi MPFI unit
New cap, rotor
Plug wires are on the way
New Coolant temperature sensor
I ran a test to eliminate heat from the equation by switching on the key in the morning and then not cranking it until a couple hours later. I had to hold WOT to get it to start up after doing that.
Any fresh thoughts would be appreciated.
