my 4unner threw a check enging light today.

i noticed it after i had been running around town, trying to hustle, so i was shifting at about 3800-4000rpm. it threw the light about a block from home.
my friends wedding was today, and i had a ton of stuff to do all around town.

now the engine idles at 1000 adn the exhaust smells a little richer than before.

any ideas?
200xxx on origional O2's.

Which terminals do i need to jumper to get the code?


just when i though i had some money to put into savings....

 

Might be your o2 sensor, your engine will run richer if they go bad. I'll be able to tell you the terminal placement later today.
