Rebuild running rich....with flames!
Ok, well first off let me give you some background on my motor. I rebuilt it with the RA kit and did a large street port(ito porting template) to be exact. It has ebay hard pipes and kn filters, hks downpipe, and a hks hipower exhaust. I fired it up today and i had a hard time gettin it to go but after giving it some gas i could keep it at 2k. It was loud and kinda rough I let it run longer for about 30min, turned it off to go inside then went back out and turned it on. I checked all fluids and topped everything off. Right now i can keep a steady idle at about 1.5k. Everything appears to be running cool and im pulling 10in of vac. I drove it around the block keeping it under 2.5k and when i came back i had flames while idling. I turned it off and turned it back on and no flames, drove it again and flames again! I reved the engine to like 2.5k and shot like a 4 foot flames, and again little flames while idling. What is going on? Im breaking it in as directed. I think theres also air comming out of my BOV when idling. Do i need a pfc already or what? Im scared to drive this thing around like this. Any help will be appreciated. Thanks!

there's a thread right now in the 3rd gen classifieds with a few guys (myself included) trying to get a group buy direct from the same company doing the ebay auction. Last time I checked we had 3 and we just started looking for people today. Once we hit 10 that should give us some bargaining power.

I ordered mine from them and there is a long wait. Took about a month to get and the directions were in japanese but it works and the controller is in english so why not. good communication too

How long was your car down for before you had it all back together again ?
What does the exhaust smell like ? Color of smoke if any ? Have you checked your fuel pressure at idle ? Actually does it idle at all ? What kind of vacuum are you seeing at idle ?

My car was down for 3 months. The exhaust smoked for a while with light white smoke then it went away. Its smokes for a little bit until it warms up then it goes away. The exhaust smells rich, like really rich, It burns my eyes. It idles ok from around 1.3-1.5k, but only after it warms up. Sometimes it dies right away after starting unless i keep it at like 1.5-2k for a few minutes. Ive been getting 10in of vac at around the lowest idle. Anywhere past 1.7k i start getting boost. I havent checked my fuel pressure.

After reading this thread, https://www.rx7club.com/3rd-generation-specific-1993-2002-16/still-running-rich-other-problems-401456/ it seems that im running rich because of my porting. Because of the porting, the engine is not pulling as much vacuum as would a non ported engine, therefore the stock ecu is adding fuel to compensate.

Installing a PFC is not going to fix your problem. Jesus people, he's talking about FLAMES. He's got a basically stock car with a streetport. It should run just fine with the stock ecu. Depending on the size of the port, I suppose it could certainly idle a bit funky, but not anything like what you are experiencing....
You have some issue with the rebuild/reinstall, period. Get back to basics and start troubleshooting.

If you ask me you vacuum is low. My guess is as others have stated you have a leak somewhere either vacuum related or perhaps LIM is leaking. Your BOV should not be venting either.

i just realized that the hose going from the turbo inlet to the oil filler isnt connected, i doubt that would make a difference but its possible. any one know? I took off my UIM today and im going to retrace all the vac lines and make sure everything is ok

On my first rebuild I messed up too and it sounds like what mine did. I ported everythingIt was only a racing beat template but I did the secondaries and the primaries. The motor still runs today years later on a E6k but still has the idleing fireball problem.
(yes I sold the car like that)
Yes I've learned since then only port the secondaries!
Anyway good luck 209FD
