hi last month the check engine light went on i found out i had a p0155 code the 02 sensor so i left it. then i had a fire in the engine not bad just the cap was left off after the oil change and i drove for a while until i saw smoke oil was spraying on the exhaust shield. there was a small fire on the shield so someone sprayed a fire extinguisher in there but it got all in the valve cover. so i had it towed to a garage the cleaned everything out and changed the oil.
now after a week or so i go to emission and fail i got two new codes now p0173 and p0170 is that from the fire and what are they

P0170 Fuel Trim Malfunction (Bank 1)

P0173 Fuel Trim Malfunction (Bank 2)

There are a lot of problems that can cause these codes to show up but the most common is a vacuum leak. Maybe something melted?

Hello,
I'm curious to find out if you were able to clear the codes. What was causing the codes to come up?
