11996 Mazda B2300 - Bucking at low RPM, rough starting, stalling

Maintenance/Repairs

Truck has 150000 miles. Very suddenly one day it started bucking violently. Replaced fuel filter, wires, plugs and crankshaft sensor. The bucking became less violent and only happens at low RPM (around 2000 or less).

Replaced the coil but that didn’t seem to make any improvement.

It’s also tough to start, and often when it starts, it will stall when I engage the clutch and move. THEN it is very hard to start, often only starting if I keep the starter kicking it over as it’s trying to start up (just put in a new starter!).

The engine seems strong when it runs. But this problem is driving me nuts! Any help you can offer would be GREATLY appreciated!
