Looked through youtube videos for cleaning fuel injectors. Don't remember the exact one but watched a few of them. I did not spray through the injectors using external electric pump.. just cleaned them with carb cleaner

 

Did you use the method of hooking up power to it and spraying carb cleaner into a plastic syringe?

 

No - did not do that - just used a tooth brush, carb cleaner and cleaned it gently

 

Okay thank you. I'm going to clean the fuel injectors for the p0170 and replace both EVAP parts you listed for my code P1457. I changed out my catalytic about 2 months ago, spark plug wires about 6 months ago, new filter not too long ago. Although, it has been about a year since i changed my spark plugs.
