i recently picked up a 95 4dr civic ferio with a fresh rebuilt z6 swap with a y8 skunk2 intake mani 4-2-1 headers blah blah all that is un needed info but my problem is when i got it the kid gave me an extra throttle body because he put a b16 one on there and the tps is shot so it idled a lil high but ran fine so i went to switch em out but the new one had a shitty ficv on it so i just put the old one back and put everything back how it was and now all of a sudden it wont idle at all on start up and idles at like 150-200rpms after warm up and i messed with the throttle set screw and stuff already and 200 is the highest i got with it all the way out im tempted to just sell it but i really dont wanna can anyone help maybe had this problem before it also could be off time because the kid didnt tighten the crank pulley bolt or somethin and it shot off while i was driving the other day but ima check that so any suggestion minus the timing part idk for sure if its off havnt looked but gonna check it out!

 

check to make sure the tps and the map sensor plugs arnt switched cause they will plug into one another and they are both on the tb
