Why does your Mercury Capri have rough idle loss of power on acceleration and check engine light is on and miss fire?

The rough idle, loss of power on acceleration, check engine light, and misfire in your Mercury Capri could be due to several issues, such as faulty spark plugs or ignition coils, which can cause misfiring and affect engine performance. Additionally, a clogged fuel filter or failing fuel pump may restrict fuel flow, leading to power loss. Another possibility is an intake or vacuum leak, which can disrupt the air-fuel mixture. It's advisable to run a diagnostic scan to pinpoint the specific cause based on the error codes.
