Running Rich, Not Sure Why?
Running Rich, Not Sure Why?
Here is a link to my build. Sorry its on another site.
http://forums.nicoclub.com/cj-s-build-t425480.html
So, I finally got my car running. But it is running super rich. My wideband says its at 10. Its blowing alot of smoke. When I had the turbo on i didn't have this issue. Now its N/A.
Info:
93 KA24DE
Motor is stock
Cometic head gasket
ARP head studs
All new gaskets everywhere
Ported intake mani
Emissions removed (EGR and everything)
Turbo mani with "turbo delete pipe" and full 3" straight pipe. No cat/resonater/muffler
Walbro 255 fuel pump
300zx TT fuel filter
stock fuel rail with stock injectors with stock FPR
All stock sensors
stock ECU
Dont know if there is anything else to list. One idea I got from talking with iLL Garage is a bad O2 sensor. Anyone else have any idea?

An exhaust leak even in a turbo car shouldn't cause it to run rich, especially at idle! At WOT, unless it's big enough to let enough exhaust pressure out to prevent the turbo from spooling all the way, and he's on a ROM tune at a specified boost level which the turbo cannot achieve.
An exhaust leak that big would sound like a nightmare of a wastegate, aka a hole in the manifold And oh wait, he's not running a turbo at the moment anyways
CJ, if my coolant temp sensor gets unhooked, that's exactly what happens. It idles like a pig and blows out black smoke at 10:1 AFR

+1. It only pushes 2-3 more psi than stock. This will not drastically change the tune/afr's. I ran this n/a as well with no issues.
It seems that he didn't even touch the injectors so the likelihood of them leaking is slim to known. Coolant temp or something similar. Maybe fouled plugs. Hard to tell without knowing what's up or what he did.
