This is a 1989 Toyota pickup 3VZE 4WD. The thing starts first thing in the morning , drives with no issues at all to wherever I go as long as I don't stop along the way to grab a cup of coffee or do errands; if I do stop, when I try to start it again it just cranks , before i was gassing it while it cranked and got it to run again, but now even that technique is not working ;but if I let it sit for hours at a time it will start again without problem but the stop issues are there.

One thing i had noticed lately , is that the idle was getting rough.

Been reading all the boards trying to gather information .

Thanks for the input.

 

Easy part to eliminate:
All temp sensors AND THEIR MOUNTING THREADS need to be cleaned once every 29 years
Clean both on sensor and on block down to bare, shiny metal. Do not use insulating sealant on threads of sensors with only one wire.
