Timing chain/belt issues

The K20A3 engine uses a timing chain which can stretch over time, leading to poor engine performance or failure.

Ignition coil failure

Can cause misfires and poor engine performance.

Oxygen sensor failure

Leads to poor fuel economy and increased emissions.

Throttle body issues

Build-up of carbon deposits can cause poor acceleration and stalling.

Valve adjustment

In-line engines like the K20A3 may require periodic valve adjustments to maintain performance.

Egr valve problems

Can cause rough idling and poor acceleration due to carbon build-up or valve failure.
