i have been runing excessive lean, po171. i have a loss in power and want to know what is the next upgrade to consider in getting back the power ive lost. along with the traction control keep turning off when the check enging light comes on or not.
It sounds more like a maintenance issue than a tuning issue. The mods in your registry should not cause a lean code or loss of power. Maybe its a bad O2 sensor or another sensor?
i have tried every thing, is not the o2 sensor at all, ive change the fuel filter, tryed injector cleaner, cleaned the MAF. id check the vacume lines,. i havent check the proper feul pressure yet or check if my MAF is working like is supposed to. its been tuning off and stay off for a while then come back on after a few starts.
Our cars do not have MAF sensors (mass airflow) We have a 1 Bar MAP (manifold absolute pressure) sensor, but as far as we know its only used as a load for spark tables.
I'm still inclinded to say that it is not a tuning issue, something is wrong somewhere
