Running rich & What does this connect to

[95Dsm22]

My car is running rich , I have a unknown turbo small garret probably no badge or I'd or anything have rc 550cc stock throttle body & intake Waldron 255 . The car is running rich and i'dk why , also have this connector that I can't find any info on

A picture of the plug only helps if you also include the colors of the wires going into the back of the connector. I'd recommend filing out a vehicle profile so we know what you drive and repost with the wire color so we can help you further.

I'm guessing 95-96 by lack of passenger side cas. But fill out your profile, it really helps out as Gofer mentioned.

So, how do you know it is running rich

If you just smell gas all the time welcome to the club, my car is bone stock and I get gas vapors injected into the car . You also have the breather tube vented so you're going to smell Gas all day

I have an auto meter gauge and whenever I'm driving it's always on rich , when I'm at idle drops down to stoich .

by the looks of it its for the TB or coolant area .. but really do need the wire colors and if you have 550 injector what are you using to tune with ..S-AFC, ECM Link..etc AEM ..etc etc

Haven't tuned it yet but I have ecm link , I can post the wire colors tomorrow

 

[OGDSM1989]

thats why it rich ...550's are larger injectors then our 450's... so more is being introduced into the system and poof you have a rich condition

 

[dustyboner]

its for the knock sensor

what type of air fuel gauge(wide band or narrowband)? And also if you do not have an afpr you could be potentially over running the stock regulator, which would introduce more fuel on top of having 550's. Also in the picture I can't tell, but is you bov recirculated?

 

[Dsmkauai]

Or could be for the egr! Also if you have ecmlink why havnt you changed the injector setting? Takes like a min to do

 

[Spazz526]

Definitely need to tune for the higher flowing injectors and fuel pump.

Ok so the docs I got rite now are 02 sensor heater circuit malfunction but I check and the rear o2 has been cut so not worried about that . Also volume air flow circuit malfunction and knock sensor 1 circuit malfunction . This is my first time owning a dsm so I'm fairly learning along the way. My maf was disconnected so I plugged it back in but the code came up again .

 

[95Dsm22]

That's the sensor

 

[95Dsm22]

It has a wideband , and my bov is right by the intercooler

[nwBryce89]

Are you still running stock maf? And if you are and your bov is not recirculating back into intake pipe it can cause some idle and stalling issues, I don't think that would cause it to run rich like that but just a heads up. A failing coolant temp sensor can also cause rich conditions. Have you hooked up your knock sensor and maf, if the it keeps tripping a code for maf when plugged in then it may be bad. Having your maf unplugged can also cause it to run rich since the ecu can't tell exactly how much air to account for it assumes the worst and dumps more fuel to protect itself.

 

[95Dsm22]

Yea it's the stock maf ,I have to check to see if it's connected just got it up running last week so still tweaking some things on it . It also runs hot after driving it a couple of miles . I'm going to switch the temp sensor tomorrow but Ive also seven around that there's two different temp sensors that are by the thermostat housing. I went to oriel and they have a different temp sensor other than the one that's on the car so I'm going to cut it then install the one that the have given me . I've check the fan it turns on at about 170F

You should have a total of three cts one for the Gauge one for the ecu and one for the a/c. You need to check out the one for the ecu, should be on the thermostat housing with the one for the Gauge just make sure your swapping the right one. You need to get yourself a digital multimeter and build a boost leak tester if you plan on working on these cars , this way you are not just throwing parts at it.

ok im going to be swapping it today hopefully that would be it , and also the sensor turns out to be the knock sensor and the connection for it is right by the fuel rail but i dont have it ? i wonder whhy

 

[Boost-Junkie]

if you plugged in the maf as you stated and the code came back on, there is definitely an issue there. At idle airflow across the sensor is low so you will see stoics readings, but under load It's rare but maf readings can be higher than actual because of an innacurate sensor sending the system rich

How is your gauge setup by the way because if when you come down to idle on a rich condition your gauge would come up, not down ( down would mean lean) just trying to clarify first
