Question about 1992 GMC Sierra
Runs rough till warmed up. Hesitates. Surges. I put a new TPG on it, carb cleaner, new O2 sensor
Ok, you got new 02 sensors, that is good, Now check timing, vacuum hoses for leaks, check for headgasket leak with compression test, Check or change fuel filter and plug wires. If fuel injected, try using injector cleaner and you can also remove one injector at a time to make sure it is not leaking or plugged. You can also test throttle position sensor and idle position sensor with an ohmmeter to see if they are good.
