What is the exact code number not code description?I would be looking for a vacuum leak first with that code.
I do not know the code number the guy at Advance Auto did not give me one. I looked at the readout and all it said was lean on bank 2
Its a lot better to have the code numbers when you look up the codes to get you the trouble trees the exact numbers are needed.
I had a vacuum leak repaired recently. How many types of vacuum leaks are possible?
There is manifold ported and ventri the leak you would be looking for would be a manifold vacuum leak.Again the code number would be great.Have you looked for another vacuum leak?
No, I have not. I don't know where to begin looking for a vacuum leak. Any help would be greatly appreciated.
You would let it idle get some carb spray and spray around the intake all the vacuum hoses etc and listen fir idle to go up down stumble or die.
