How would someone know it there car is running lean or rich? is there any easy way of telling if the car is running too lean or too rich..thanx

 

Get an air/fuel guage. There are a lot of ways to check. You can check your plugs for a start.

 

wat color will the plugs be if its runing to rich or lean? thank you

 

white = lean
black/wet = rich
(most honda's idle lean though)
smell the exhaust if it smells a lot like fuel you're rich.

 

plug electrodes should look like coffee with cream. The base ring should have a thin layer of carbon all the way around, with no buildup anywhere on the unit.

Rich = smells like mad fuel, gas runs out quick...car doesnt feel like its moving when you do a full throttle...etc. Couple things...Im no pro, but my car is currently runing too damn rich and in the middle of tuning it right now.

 

I have a queston, I just put in new plugs like a week ago and there is already carbon buildup on the second day of running them. Is that normal? This is on a d16z6.

 

Carbon build up should be fine...if you see fuel in there, then thats a no no.
