Question about 2005 Toyota Corolla
Too lean bank 1
the code that i got is p0171
iam trying to fix it help:O)
You probably have a vacuum/air intake leak.
With the engine idling, spray very short bursts of starting fluid/ether around the intake and surrounding engine bay and wait a second. If the engine surges, there is an intake leak which you can identify by closing in with the ether.
ALWAYS USE VERY SMALL SQUIRTS IN A DIRECTED AREA AND WAIT FOR IT TO VENTILATE BEFORE TRYING AGAIN ELSEWHERE
Put car outside,
do this in a ventilated area,
have a blanket handy in case of a backfire fire.
DONT spray ether idirectly into the air intake when the engine is running
A bad intake leak is audible by a hissing sound. A bad rubber hose is often the cause.
Any vacuum hose under the hood can cause this.
The PCV valve which can also cause this code when faulty, should be replaced as a matter of course. its in the valve cover and only costs a coupla bucks. They are easy to fit.
Hope that helps
pls be conservative with the ether its not good for your engine in large doses!!
