Hi I'm Wayne

I will help you with this

Yes bad fuel will do that

the only way to check them

is bring them to injection shop and have them POP TEST them

no ryme or reason for 2 just 2 to fail,

you can also switch the 2 out with 2 others, ,and see if you get the same code

Customer: replied 1 year ago.
sorry confused with your answer are you saying bad fuel can cause just to cylinders to perform bad or do you mean two faulty injectors,also problem will come and go sometimes only 8001 code come on only
Expert:  Wayne replied 1 year ago.


Yes 2 faulty injectors from poor fuel

switched them around with 2 other cylinders

see if the issue moves or stays there on 1 & 2

Customer: replied 1 year ago.
ok & if i switch them & codes change does that mean i have faulty injectors & if they dont change where do i go from there also my question earlier how can i test for bad fuel
Expert:  Wayne replied 1 year ago.


The only way to test for poor fuel is bring a sample to

fuel/oil analyst, or they sell a paste that you can check for water in the fuel

it is gray, if water turns blue

yes, if the code changes then you know the injectors are faulty

Customer: replied 1 year ago.
even if both fuel injectors are new installed few weeks ago and if code does not change where do i go from there
