• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

AEM Air/fuel mixture gauge hook up

That's not the right grommet then. From inside the car it's up even higher, and slightly closer to the driver's side. You just have to pull the carpet down a little bit, and reach your arm up under the rubber padding, there's a stiff cable going through there (think it's the hood release, but I can't be sure)

It's got a round rubber plug that you can either pop out of place, or you can puncture to feed a wire through (I used the prior option)

I didn't see that one.

There is a floor gromment on the passenger side, that has a huge harness going through it to the under hood fuse box/battery location. I use that one because it's near the exhaust.

So, I need to punch a hole big enough to get the connector for the sensor through. Maybe just s slit.

Sorry for all the dumb azz questions. I'm learning as i go......
 


pretty sure most drill a hole in the rubber block on the pass side floor. watch out for the wires in the block tho.

for the fire wall grommet, i've used a hanger, cut down to 6 inches or so, and tape the wire to the coat hanger and pushed the hanger through then find it on the inside and pull it through. called a fish tape pretty much.

That's what I plan on trying later today..... Don't know what I'm going to do next tho.

Maybe find out why #2 cylinder is misfiring.
 
Well, I knew this Long screwdriver was going to come in handy........

I taped the sensor wire to it and ran them through the firewall.

Worked like a charm.....unfortunately, I couldn't get the factory sensor out of it's hole...........

they sell a o2 socket, as well as a wrench, or a line wrench works well. then if using a wrench hook another wrench on the end of it for more leverage.

Again, if you do not have the ability to TUNE the PCM, removing the stock narrowband O2 sensor will cause problems!!!

is there something you're missing from this information?

If you DO have a tuner, you can remove the O2 codes & diagnostic checks and put the engine in open loop in absence of the O2 sensor. A wideband in place of an O2 is not going to work otherwise... There's nothing telling the engine what is happening from the fueling/combustion.

therefore, take it to a muffler shop and have em weld in an extra bung as per instructions so you can have both the stock and wideband.

Good luck!
 
his car is tuned to some degree, if the cel for a o2 is not on its been tuned out, being its not plugged in.

he got this car like a 1/2 asses tossed together turbo set up. hes still working all the bugs out of it little by little.

this is just one of the few things hes working on atm.

If removing a sensor that's not connected to anything is going to cause problems.....I definitely AM missing something.....

Easy now...I'm slowly but surely getting this ride together. AND it WAS tuned by some "tuning guru" in Michigan.

PO said the car has "cat delete" what (other than it has no cat) does that mean?
 
We established the fact that you have no rear o2 sensor in your last exhaust thread and that if you had no code for it then it likely had been tuned out...remember.
From the pictures you've posted I'm seeing two o2 sensors currently plugged/screwed in to your car, you have one in the stock location in the bung in the rear manifold and one in the downpipe.

Alot of turbo setups have the bung in the downpipe with the narrow band o2 connected there and have the stock bung in the rear exhaust manifold capped.
Did some one get lazy and leave a narrow band in there unplugged instead of capping the bung hole?
Guessing the o2 sensor in the downpipe is connected to the wiring harness and the one in the rear manifold is not?
Not sure what you have going on, can't see where any wiring is going with your close up pics.
Do you have the WB o2 sensor that came with the AEM kit that was with the car?
