redtop running rough

[ezyride]

I just did the swap.. Car starts nice. When revving between 3500-4000 rpms it runs like shit sputtering. then it stalls when we let off.

ecu code 55 on ecu..

pulled a test on maf.. Plug and unplug.. Seems to run the same but with it unpluged u get a code and it doesn't run pass 2500rpms. with it plug no codes and passes 2500

would bad maf do this??

Replaced Maf Fixed The Problem..

Car Idles Low.. After Revving It Stalls.. Does Anyone Know How To Adjust This..???

Timing Is At 15..

Does anyone know how to set up the cold idle??

not sure about setting a cold idle, but i would just let the car warm up and then unplug the tps and adjust the AICV to about 1000. if that is stable there then you can expect around i dunno 1500 on cold idle. do you have a blow through or draw through maf setup? have you tried tightening your BOV? checked for vacumm leaks? what exactly did you FIX by changing the MAFS?
