ok my ssei is idling really rough rpms up and down sometimes even cuts off and when im driving it sometimes putts a little bit under normal driving and when i go WOT it putts a lot sometimes ne i deas. i have new plugs new MAF and a new O2wires arent brand new but their accel 8mm they have some miles on them tho

have you checked your coils using the procedure in techinfo? Have you checked your plugs?

Did you gap your plugs?

was it doing this before the tuneup?

Another idea is that often overlooked is to make sure the rear wires are not touching the O2 sensor and did you take the plug/wire out one at a time so you get the right wire hooked to the right coil?

Have you checked your catalityc converter? I had similiar issues with mine once and tha cat was all clogged up and needed replacement. Supposedly you should be able to hit it with a screwdriver and if you hear stuff boucing around inside, it'* bad.

When mine went bad I also had a hint of white smoke (Actuallt more like white powder) coming out of the tail pipes when I wnet WOT from a stop. I did some testing at home and found tiny bits of the cat'* honeycomb intereior coming out.

I replaced my exhaust including the cat on back, and everything was fine again. Not saying you shoul dgo rpelace the smae, but look there as a possible cause.

my plugs r brand new and bfor i did the plugs my car was runnin worse cuz i had to swap out superchargers and my maf sensor was skrewed. i was just driving and it was puttin pretty bad and it cut off and wouldnt start. the speed gauge was still workin and after it sat for a min it started and ran for about 5 min i had it at 2000 rpm to see if it was missing bad or not and cut right back off and wouldnt start again and let it sit and started again. my grandpa said it might b my fuel pump and i think it might be i have a nitrous system half way hooked up all i have is the fuel hooked up and i sprayed it to see if i had pressure and i did but at one point it didnt have ne at all so i think i might change the pump and see how she acts then. sound good?

Sounds confusing.

Where did you get the new supercharger? Did you use all new gaskets and possibly replace the o rings on the injectors?

i got the supercharger from the junk yard but it works fine no play in the pulley no noise its fine and the car has been running messed up since i got it i only paid 600$ for it so i know i had some work but i didnt think id have so much wrong with it the maf sensor was shot thats why i changed it i figured id go ahead and change the o2 sensor jus because. the gaskets i changed of course and made sure i cleaned the supercharger and the lower intake manifold. my grandpa thinks my lower intake gasket might be leakin and we sprayed so carb cleaner in a spot and it ran better till we stoped sprayin it so i dont know im about to put in a shop and let them deaal with it

ok its not the fuel pump. i have 41-42 key on car off and bout 35 at idle and goes to about 45 wot. so the pump is out of the question. the pressure is fine when the car acts up and cuts but the needle on the pressure tester pulse real fast doesnt move much but it does pulse. next im goin to check the coils ne one have ne thing that they think might be halpful pleassssse let me hear it
