Question about 2001 Chevrolet Cavalier
The yellow emission engine light comes on.It reads a code of 442 for a small emission leak. What things should i check for a leak and where are they?
To find a leak in a vapor hose, you may need a leak detector that uses smoke and/or dye. A 0.020" hole is the size of a pin. it can be a pain to find .This is about the best alternative. You will probably need a mechanic for that.

Is that P0442?, if so it may be due to a loose gas cap or leaking gas cap check valve.
