Im having throttle problems i fixed the first problem. Which was my throttle would only open a quarter way so i swapped throttle bodies. Now the problem is it spits and sparks around 6000 rpms and drops to around 1000 2500 rpms then after about a min. Or two it idles rough between 500 and about 1800 rpms. Ive been hearing about the tps and the throttle plate being open a bit. Ultimatly think i need to tps. But im broke and dont really know how to fix it. So how would i fix it or in highschooler terms (timing the idle and rpms)

 

http://www.rx7club.com/2nd-generatio...-101-a-235007/ see Aaroncake's post for setting the tps. Did you clean the throttle body and set the throttle plates properly before you put it on also? You should post these threads in the main 2nd gen specific section. I would imagine your afm could be a potential player in your problem but I'd sort the tps and throttle body first.
