Find the stall,
not the parts cannon

Pick year, F-150 / F-250 / F-350, and the engine that is actually in the truck. The oval pulls pinpoint tests, specs, and code charts for that configuration — TFI gas, 7.3 IDI, Power Stroke, and the 1997 F-150 Tritons.

OBS fact

OBS is shop slang for Old Body Style — the 9th-gen trucks after Ford restyled the F-150 in 1997.

Waiting on the oval

Nothing is guessed until you hit the oval. Results stay locked to this year, series, and engine — and any symptom you typed.
