Blower motor and speed control operates properly.

Oxygen sensors (3) replaced to correct rough engine performance. Mass air flow sensor also checked. Now the engine will race on its own several times in a short trip.

The hoses to the heater core appear to have pin holes in them. Are they special molded bends OEM. Or can normal hoses be used to replace and is it a DIY?
