Just bought a 2000 expy and been reading up on the "THINGS TO DO" to get better gas milage and performance out of it.
First thing i have done is added a K&N Air filter kit. That is it for the moment.
Now after 180 miles on the new air filter i am getting an engine light, which is telling me the #1 and #2 banks are lean???. I am hoping that is has to do with the air filter upgrade i did and not something i got stuck with from the previous owner.....i have read that some people have put in a diferrent air flow sensor ????not sure if it was for the same troulble i am having or not.
Thanks for your time,
Patrick
