Hi All,
I was looking for some suggestions for what is causing my 1991 Toyota V6 3.0 to be showing codes 25 & 26 which I believe are too lean and too rich. When I clear these codes it always takes longer for the 26 code(too rich) to come up probably next morning when started cold. The following are things I have checked for:
Vacuum leaks
MAF is very clean
Fuel filter has about 18,000 mile on it.
Just had complete tune up. Plugs, rotor, Cap, plug wires and fresh air filter
Mechanic checked both oxigen sensor's and seemed to be doing thier job
As far as how it runs, it runs very good and strong, only exception is a slightly rough idle but smooths out quickly when giving it the gas. I'm about to give up on it and just put black electrical tape over the check engine light and forgetting about it I'm presntly not at home and will not have a chance to take it to my regular mechanic until April. Maybe there is something simple i'm missing?
Thanks in advance,
Bob
