i just replace my old stock injectors with new stock injectors and i keep fouling all my plugs out but the third on start up is there anyone that might have a idea why?

 

Why did you swap injectors? Are you sure you have stock injectors now?

 

well see i had put 780 in my car for a new turbo i had bought and im still waiting on it i though i world get it quicker so i did injector swap and decided to put the stocks back in because it will be a while before i get it but they injector are the stocks that came out of the car so i do not understand whats going on and the plugs were brand new to

 

Did you scale the 780's?

 

no all i did when they were in was start the car and let it idle to check for leak but they were never scaled and no tuning was done

 

Reset your ECU, maybe in the short time you had the 780s installed it upset your fuel trims.

 

i have unhooked the battery and cleaned the plugs but it still fouls them out.the tips are really black looking and they smell like gas real bad

 

Maybe a big air leak post MAF.

 

im just going to put the 780s back in and wait for the turbo and get tuned and see what happens o well thanks though

 

running too rich

 

is it possible that putting the injectors in a different spot in the intake manifold then they were orignally might cause the fouling ?because the third plug is fine.this is just a though maybe someone can help on this
