SOURCE: 1987 F 150 Problem: engine idle stalling and then surges
Here is a idea, there is a small rubber tube connected to the bottom of the throttle body, it is a vacuum line. It is located under the breather hose where it connects to the intake. This tube is located near the Throttle Positioning Sensor, If it is cracked or has come off, it will make the engine surge.

Hello;
Several things can be causing your problems. irst check your fuel pressure. Also check vacuum hoses for any leaks. Any codes for additional diagnostics?
Thanks;

Listen before you spend the money try a simple thing first. At our shop we start with the EGR solenoid, locate it, remove it, make sure that the ports are clear. Carbon build can cause your symptoms

Check the pcv hose for leaks at the intake manifold. Common problem.
