ok guys i got a question. i have 1997 civic ex. it had the y8 motor in it and it was about to throw a rod. so i picked up a y7 off a friend real cheap. i installed it and it runs good but has a check engine light and wont rev past 5500 rpms. im still running my vtec computer on the non-vtec engine. so i tried puttin a y7 non vtec computer in it from a dx and it starts but shuts off automatically i have to give it gas to stay running. any ideas guys???

get the cel codes and still... check your map and tps, and try another p2e ecu, or whatever non vtec ecu your using.
