Okay, enough is enough and I need help.

Car 1995 240sx Le
KA24de obd1

So the other day i decided to change my tps because i was tired of sputtering sometimes durring acceleration. I didnt o any research on replacing it, though i could just unplug it and change it out just like a MAF. Wrong!!!! So after I put everything back together with the newer tps( from an auto 96 obd1 ) it wouldnt stay on could not idle. Then come to notice i had a slit in my intake piece. I taped that off and put back the old tps ....and it ran fine but idled at 1100 and at traffic lights would rev up and then rev down. At one point i had to keep the a/c so it could idle somewhat right and feel good. Then this past weekend...i decided maybe it was doing that ruff idle cuz of the slit. so i went back to the (96 obd1 tps) .....and it left me with hardly an idle...so then went back to the orginal tps this morning and now i have to keep my foot on the gas so it can stay on. it sounds horrible. drives horrible. Somebody please help me please......
