Why's My Car Running Rich?
#1
OK, it's got a full exhaust (over 3", minus the midpipe, which is 2.75 ID.), apexi intakes, and a Koyo radiator.
If anything I would think it would run lean... But it's fouled out a set of platinum NGK's in like 10 miles! Running on one rotor now.... and I'm stumped.
Does the ECU have any kind of a limp mode were it runs rich? I haven't installed my boost guage yet, but I thought it was hitting fuel cut (the 2 times it did it), but it also felt like limp mode in the series 5's. Before I blow another $30 on a set of plugs, I would like to figure this out

I've got an RE boost guage/pettit column pod... it just got here today, but since I'm a friggin moron, I looked myself out of our gaurage.... So I've got to wait till my step-dad gets home with another key
Also, I swear, I was just searching on limp mode/ECU codes, and I was reading alot about the map sensor, and replacing the vacume line... then I was like, "wait... map sensor??? Were's that? It's got a vacume line????" "****..."
And of course, now thinking about it, I never hooked it up (other than plugging it in...) And I feel like a ****** idiot

Well, since it was in the wreck, the nipple was broken off of the bottom of the boost sensor, so neither of us noticed it....
Anyways, got it hooked back up, and once I get a new set of plugs tommorow, I'll see if that is the problem.

Well hooking up that line, and a new set of plugs got the engine running good
But now worse than before I've got smoke pooring from the passengers side of the enigne, it's oil burning.
And I truely did hit fuel cut this time It came about when the secondary turbo kicked in.... felt a really hard pull... the just like it died.... Time for a Redom huh???

you dont have to keep replacing yoru plugs they might still be good... spray it with brake cleaner and brush it with a silver steel brush(none of that bronze stuff) rinse it off and spray it with brake cleaner again and light it up with a butane lighter

It hit them with an abrasive pad, then got them with the butane tourch, and they didn't work at all....
Anyways, it seems that I only get the smoke after the secondary boosts a little. (I don't think it's doing much, because once it get some boost, the engine pretty much falls on it face....)
If it just idles, or is driven lightly, it has no smoke.

OK, in 1st gear, it will hit .8 bar of boost (reading on my mechanical RE gauge.) Then it cuts out/falls on it's face... whatever.
In 2nd/3rd it will hit about 1.2 bar of boost, then cut out.
So this is fuel cut, and I need an upgraded ECU correct?
