A YD25 engine may lose power due to several factors, including a clogged air filter that restricts airflow, a failing turbocharger that affects boost pressure, or fuel delivery issues such as a clogged fuel filter or failing fuel pump. Other potential causes include ignition system problems, such as worn spark plugs or faulty ignition coils, and engine management issues where the ECU is not optimizing performance. Additionally, low compression due to wear or mechanical failure can also lead to a noticeable loss of power. Regular maintenance and diagnostics are essential to identify and resolve these issues.

What would cause severe engine power loss and the service engine light to come on in a 1987 S-10 Chevy blazer after about ten miles of driving?
The first thing that comes to mind is the catalytic converter plugging up after driving a short distance and clearing itself after sitting for a period of time. Take it to a muffler shop for an expert opinion. The plugging of the converter would cause a huge power loss and the resulting restricted exhaust gasses would cause your check engine light to come on since the oxygen sensor would be giving the computer bad information.
