Well I just got ngk plugs and wires from advance auto. I hope this fixes the problem.

aside from this stutter problem, the car has been idling like SHIIIEEEEET. If I give it a constant gas to keep it at 1200 or so rpms, it still stutters real bad. when I drive, it stutters as im driving. Same thing whether the engine is cold or hot. One thing I dont understand though is that its intermittent. One day, it could be idling bad, almost stalling out, all that bad stuff, and then the next day it will idle fine. Sometimes I'll start it up and it idles bad, then ill start it up an hour later or so after i drive it and it idles good, and vice versa. the air/fuel gauge almost always shows it buried in the lean, sometimes just a faint light, its so lean. the egt gets higher than usual and stays up there longer. I'm running a +12 on the safc(+16 at 1000 rpms, then 12 the rest of the way, all this on "low-throttle" setting, stock injectors and 16psi). Why would the car run lean and crappy one day, and then be running fine and smooth the next? No matter what the car is running like, it still does the backfiring(or whatever) when I'm getting on it.

Also, could this problem have anything to do with what type of oil I use? I just did an oil change about 1 month ago and used quaker state 5w30 full synthetic, and I put a bottle of bars leak oil conditioner in. the car ran pretty good for a while, then back to its crappy tendencies.

thanks for any help
