MX-3 engine swap

[GirlieGirL]

hey.
I have a '93 MX-3, and I just did an engine swap in it. I now have in it a Japanese Eunos. It's running incredibly rich,and it's got an irregular idle. Any one have any ideas of what could be going on?
Thanks for any help.

what j-spec motor do you have? 1.8 or 2.5? if it's the 2.5 kl-ze, it depends on what ecu you are using. check out mx-3.com if you haven't already. there is a ton of info there.

I have the j-spec kl-ze 2.5.
I took it to Mazda and they said that the problem was my o2 sensor, so I bought a new one, and it didn't help. bah. so now i'm out the money from the o2 sensor, and still have to take it back to Mazda to figure out what is wrong.

don't take it to the dealer. with you having a motor swap, they'll rip you a new one. they don't know jack about this setup. many people have had this problem with the 2.5. go to www.mx-3.com and go the the forum. there's a v6 section. they will be able to help you out.
