Misfiring
Hello i have a 1996 lexus sc400. I’ve been so upset with this car . I bought this car as my first “cool car “ and it ran good for a few months until it started misfiring horribly. I did the spark plugs , checked the coil packs and did the injectors but i’m still misfiring . please help

is there any codes coming up or are you just feeling/hearing it? and if you've done all that then I think the popular answer round these parts are 3 dreaded letter "ECU" but I'm just talking outta my....butt as i don't have enough information here.

If you turn the car on at night, it would be easier to spot if you have a misfire, because that cat will light up in the dark. This may cause damage to the cat, so I wouldn't do it unless it is absolutely necessary, and you don't know where the misfire is. Check gaps on the spark plugs, and inspect for any foreign debris. Other than that I would check ignitors if it has them. I'm unfamiliar with the newer coil packed ones and am unsure if this is of any help.
