I poured a bottle of fuel injector cleaner into my gas tank and now my engine is running lean. I'm on my second gas tank now and I'm still running lean.

Will my car ever burn normal? How do I fix this problem? Even my "Service Engine Soon" light is lit up!

Any advice?

How do you know it's actually lean? What are we talking about for a car? (year, engine, mods, etc)

 

Hey All,

After my second gas tank, I burned all the injector cleaner out of the system and my engine is burning normally again.

Thanks!

I have sensors hooked up to my O2 sensors and they flash red/green for lean/rich. It's crucial to know if you're burning lean or rich before you squeeze nitrous!
