i got a 99 sunfire 2.4 with 80 000kms when tis idoling and i hit the gas it puffs black smoke a lil what can this be..to rich and if soo how do i adjust it
First of all are u getting check engine light on? If so i would get the code scanned then start from there.
Good Luck.
Black is rich, blue is oil.
Really the only thing I can think of that wouldn't throw a code would be your FPR malfunctioning. Other than checking your fuel pressure or scanning for codes (maybe your MAP going bad).... tunning is really the only way I can think of to "adjust" it.
No adjustment. Its too rich. Double check your MAP sensor on a scantool and verify it is working correctly.

Does it matter that the car dont have a cat on it..i got it with no cat and some fart can type muffler and i changed it back to the gt dual exhuast..it only smokes at start up and when u floor the gas...thanks for the info guys
yeah, no cat will increase your carbon exhaust quite a bit....
put one on, problem solved.
Not saying that the cat is not the problem, but i haven't had a cat on my car for over a year and i haven't got one puff of smoke yet out my exhaust (minus the sea foam experiment)
