Bled a little more air out of the cooling system. Its a steady stream into the overflow so lets hope im done.
the o2 heater relay circuit is repaired but the car still falls on its face and doesnt run when warm unless the o2 is unplugged.
I suspect the solution will be found in one of these:
-new o2 sensor
-new DME
-ensure there are no upstream air leaks.
This exhaust system is the biggest pile of crap ever and the guy that did it sucks. I didnt know how poor of a job he did until i got home and took a better look underneath. Im living with it for now and have only scraped on my driveway entrance when i cant take it at an angle. Tonight it caught and pulled the band clamped portion of the system off the headers. Based on how stupid this exhaust system is I would not be surprised if an upstream air leak was throwing the o2 sensor off.
its a little too loud for my tastes and at some point tonight i need to crawl under the car and re-attach it.
My wife will not permit me to spend the money to have someone competent do the job and she is running out of patience with the car.
Its entirely possible to make this exhaust system work great but it will take someone who does quality work, and of course... money.
I feel like im at a bit of a stalemate
Voices inside my head tell me to list it on R3V for $7500 and be done with it
It drives so well with the o2 unplugged though

Sidepipes! Or a fender exit!
On a serious note, please don’t sell it. You’re too close to give up now. Seriously. Ill start another GoFundMe.

i believe i have a spare used o2 sensor around, if you want one. i think dom said he had one too. free stuff to get you one step closer!

I will probably take you up on the spare sensor.
Just to start covering my bases I began going through the suite of sensor tests in the E36 Bentley to check the resistance and reference voltage on the following sensors:
Throtte Position Sensor
Coolant Temp Sensor
Intake Temp Sensor
Mass Airflow Sensor (voltage and ground test)Everything checks out good with those. Tomorrow I will start on the oxygen sensor +related wiring testing procedures.

i have a pair of them from the e34 530 i parted (obd1 m60). not sure if they work, but you certainly can have them to try.

I used the car to run some errands and put another few miles on with the o2 unplugged. I think I have full confidence in the cooling system now. After driving, I idled in the driveway for 5 minutes with no fan and the temp stayed at 200 F (92 C thermostat). Then I tried it in the garage with hotter stagnant air and no fan and with about 10 minutes of idling. It got up around 210 F slowly but switching the fan on brought it back down to 200.
The ellipsoid I cracked the other day has been replaced.
I did a little fine adjustment on the suspension by leveling out the ride height a bit with different spring hats and spring pads. Theres a little more to do on the rear but I have the fronts leveled with eachother. They were about 3/4” different before when measuring the fender to the ground .
I may have a new lifeline for getting the exhaust tucked up a bit more, and hopefully before the E30 picnic.
im content driving around with the o2 sensor unplugged for now but I do need to replaces these brakes pretty soon.
Still no oil leaks on this engine which seems miraculous. The 24V definitely seems to have a little bit of design improvement in terms of sealing compared to the M20.
Drive by wire and automatic transmissions are deceptive. Despite being down about 65 HP from the VQ in my infiniti the M52 is a smidgen faster rolling acceleration runs, but in actual driving the infiniti feels much faster. You also end up getting 80% of the power at 60% of the throttle opening as well as the kickdown sensation.

I was about to go to sleep because ive been running on fumes the past couple days but somehow, whether through sleepwalking or poor judgement I ended up upside down under the dashboard taking the pedals apart doing something I should have done long ago.
my car was originally an automatic and when I did the manual swap I noticed my brakes werent as good after the swap. The clevis adjustment wasnt quite the same and I had forgotten about this when I did the E21 booster install so i kept the original clevis location/length. It adjusted the clevis out 3 turns which ended up being a good guess as it was the maximum amount that it could be adjusted.
It feels food to have checked that off the list because i wasnt looking forward to doing it.
im not expecting that it will affect my stopping power since its only changing pedal travel but it will definitely help with pedal feel as it wont feel like i have air in the brakes with the excess travel, it will keep the brake pedal higher for those times I want to act like a heel-toe-hero too
-
Another trustbuilding exercise: I took it on the freeway, longest drive yet and man it actually pulls pretty nice! I think my power expectations have been met.
the brakes feel better after the tired late night clevis adjustment
A woman in a new yellow audi TT, vanity plate BEVS BEE did a ricer flyby on me as well
its a good day!
Time to take it to work tomorrow!

It's tempting to dig up all the times where you expressed concern about it not being fast enough, but I'm glad it is meeting your expectations!
It's a good feeling power too, compared to an M20! -
Heavy stop and go rush hour commute. Lots of time in 1st gear and lots of time stopped. It must have some air in the cooling system still. It crept up to 220 while stopped then within a few seconds of freaking out (225 is my “shut ‘er down” temperature) it dropped quickly back to 200. It stayed right at 200 for the next 10 minutes of stop and go traffic then shot up to 220 again and i pulled over to try and bleed some air out. I didnt see anything bleed out but for the last 15 minutes of stop and go it stayed at 200 and reached a max of 205

Bleed some more or pressure bleed it next? Congrats on you successful journeys!! It feels nice just hearing of such success, it must feel even better to be driving the success!

Thanks, im still not enjoying myself in it like I should unfortunately and im burned out on working on it. Perhaps it wont sell before I have a renewed interest in continuing this dream
Where are you bleeding at? The expansion tank self bleeds the system while the engine is running. I have found it best to never open the system unless cold. You have the sending unit in the cylinder head?
Yes, sending unit is in the stock location. I am bleeding it at the thermostat housing (E39 housing has a bleeder) and also running it with the cap off at an elevated idle while squeezing hoses to watch for a steady coolant stream back into the reservoir.
