Default problem after dpfi to mpfi

alright guys i took my dx motor and used a d16z6 intake manifold and did all the wiring. the car runs but for some reason if you hold it at any rpm, besides idle. so my question is has anyone ran into this problem after you did the swap i am going back over my dist wiring to make sure its right. any help would be great thanks guys!!

dont think you wrote all you wanted to.. doesnt make sense.. did you mean that if you hold it at any rpm besides idle it stalls?

crap sorry i was in a rush and did not right the problem. yes at any rpm besides idle it will sputter and at 6k it just cuts out? that might be the stock red line, i dont know. but i have done everything rechecked the dist and tps, i dont think its my injector wiring cause it runs fine at idle. i am at a loss, i thought it might have been old fuel but i just got back from filling it up with chevron. any help would be great guys!!

its an atmospheric pressure sensor, its located under the passenger side dash, doesn't really have much to do with anything so don't worry about it... this sounds stupid, but what ecu did you switch to? and please say u switched ecus

recheck that injector wiring. If they are off but all firing it will idle fine. Also check your timing.
