1.)How do you know if the injectors are bad? symptoms?
2.)How do I test the Injectors themselves to know if they are workin properly?
3.) Is there a type of continuity check, or ohm level check to see if they are good?
I am rippin smoothy apart and i think the injectors are bad, or goin bad, but i want to be sure... so any help is appreciated...
Injectors will fail in one of two ways...
Out of Range - Will give you a CEL light, and a possible misfire.
Leaking - Will cause hard starts, and a lot of BLACK SMOKE at idle.
You will also smell a lot of raw gasoline in the exhaust.
This may cause a CEL as well.
You don't need to test them. the PCM does this every time you start your car.
If you want to clean them, get a bottle of PENZOIL GUMOUT REGANE and put it into a near empty tank and fill it up.
This is the SAFEST stuff you can use, and you will FEEL the difference, two tankfuls after you apply it.
And it lasts for a minimum 6,000 miles.
You problem is not your injectors.
Look elsewhere before you spend $$$ to replace your injectors.
