check engine light
Had check engine light at 43.000 miles. Mechanic ran diagnostic and right bank 01 o2 sensor removed and replaced. After driving aprox. 15 miles light back on again. Returned to shop and same dignostic and mechanic said he found a bad pin connection and all ok. They road tested truck about 15 miles with no light. I drive 10 miles and light back on. My question is has any one had a similar problem and also how many sensors are there, and is this covered by the emissions waranty.
thanks
