Hey maybe someone can help me out I have a 98 eclipse GS and it wont pass smog i already put a new cat on it and plugs and it still failed do you think that maybe my timeing belt cold be off a tooth or something? thanks

 

No thats not it. Do you have a check engine light.

 

No check engine light on at all but it does work.

 

Try resetting the ECU by unplugging the battery for 30 seconds

 

I did that already and it dident work you think an injector could be bad and spraying more fuel than it is supposed to?

 

hmmm... its hard to say.

You could try seafoam....

 

whats seafoam....?

 

you put it in your motor and it cleans it from the inside

 

Where do they sell it at? and it goes in the oil or the fuel?

 

Neither, although you can put it in both. You can get it from autozone.

You put it in a vacume line and it gets sucked directly into the motor.

Have you tried running the car for 20 mins before sending it in?
