how’s it going everyone!? i need help with my 92 240sx (sr20det). when i turn the car on, it idles really rough with loud coughing noise. also, heavy amount of white smoke are coming out of the exhaust (muffler). i drove the car the night before, and it was running ok. no problems at all, but when i try to start the car early today, it started acting up really weird. i’m taking my car to my mechanic tomorrow, and i’m just wondering if i can get any help or feedback here. Please help!
any help would be appreciated. thanks!
