The truck is a 1986 Ranger w/ 2.9, which has sat since 2010. The truck will idle okay for a few seconds, then the motor falls off a cliff for a couple seconds before returning to idle. We replaced the thermostat and now the truck does the same thing until it's been ran for around 10min, then it will drive normally. I took it to get gas after running it for 10min and it ran fine, but after stopping for about 15min it started bucking again on the way back (1st and 2nd gear were horrible, third a bit more manageable). Completely stumped on this one.
We replaced the fuel lines, both fuel pumps, distributor (properly timed it), spark plugs, and the plug wires prior to this issue. As well as the solenoid and positive battery cable.
Was going to try fuel injector cleaner (Seafoam) before the radiator busted, now waiting for the radiator to come in. Going to get pressure readings on the pumps as well
Any ideas what causes this? Thanks
