TURBO DLX VAN

1999 Hyundai H100 • 101,000 miles

Greetings each.
I just bought this van second hand.
It drives quite happily on start-up BUT, after around 20 miles it goes into a type of "limp mode" where the throttle becomes completely unresponsive. It is difficult to get more than 2500rpm in this condition.
If the engine is stopped and re-started all is then well again until the next time.
Any ideas please?
Many thanks.
Be good!
Cheers.

Do you have a check engine light and when was last tune-up?

Could be caused by one of the following below

Oxygen sensor.

Catalytic converter.

Fuel injectors dirty/sticking.

Mass airflow sensor/Airflow meter.

Throttle position sensor.

Crankshaft position sensor

Knock sensor

Manifold absolute pressure sensor.

EGR Valve

Fuel pressure regulator leaking or defective fuel pump.

Fuel contamination.

Foul/defective spark plugs.

Open spark plug wires.

Ignition coil/Coil packs defective.

Incorrect ignition timing.

Cap and rotor.

Note: If it doesn't apply disregard it and keep testing.
