    p219a Code

    So I know this means Bank 1 Air/Fuel Ratio Imbalance just wondering if anybody else has come across this. Possible causes listed are - Leaking or contaminated fuel injectors - Low fuel pressure or running out of fuel - Leaking evaporative emission (EVAP) canister purge valve - Exhaust or intake air system leaks - Exhaust gas recirculation (EGR) system - Positive crankcase ventilation (PCV) system is leaking or the valve is stuck open - Ignition system - Incorrectly seated engine oil dipstick, tube or oil fill cap. I'm slowing narrowing down the problems I changed the paper gaskets in the BB test pipes checked the air intake to make sure it wasn't leaking and cleaned the MAF sensor. It should not be low fuel pressure I have a BAP. I know it isn't the oil dipstick or cap, checked those. My guess would be the injectors I just recently did cam lower pulley and heads then went the cheap route with resized stock injectors. Next I'm going to attempt to switch injectors and see if the code changes. Any help Thanks...

    Did the injector o-ring issue solve the problem? I have the same issue.
