First gen NSX as in NA1/NA2 versus NC1 or do you mean pre versus post OBDII? On a pre OBDII car there are probably ways that you can block the ECU from generating an error code when you delete the EGR valve. Later OBDII cars have a lift / position pot and that might be harder to fake...

P 0430 is a front cylinder bank catalyst failure. This is most likely caused by failure of the front catalytic converter or failure of the secondary O2 sensor (outlet) on the front catalytic converter. The ECU goes into a test routine called an emission monitor to check the operation of the...

The log does not make much sense to me. It is reporting a trim for each O2 sensor. The ECU only has a bank 1 and bank 2 fuel trim which does actual fuel control and that is always derived from sensor 1. Sensor 2 is only along for the ride to determine whether the catalytic converter has...

Red arrow points to what I believe is the retaining tab. As noted by Miner, now that you have the bolster out, you should be able to release the port from the back side by pressing on that tab. Normally I have done it from the front side with a long thin flat tool. I can't remember...

I had seen that thread. It works as long as you can find a tire shop that is willing to do the tire swap.

You didn't specify your model year which affects selection. However, Centric still lists the Stoptech slotted rotors as being available for the early cars. They are probably a low sales item so they probably end up doing small production batches. If you want to try and confirm if and when...

The AAA / CAA / phone a tow truck option is viable when you confine yourself to urban environments. If you venture significantly outside of urban areas, my father-in-law discovered that he ended up with a 4 hour wait for the tow truck when he decided to exercise his CAA membership...

As ably noted by @drew, the low cost solution would likely be rebuild at home. It is typically the contacts on the solenoid that fail. Sometimes, you can pull the solenoid apart and touch up the contacts with a file and it will restore operation; however, there is a fair amount of grunt...

Some guidance on removing the knee bolster. https://www.nsxprime.com/threads/dashboard-lower-pad-removal.214410/

This was the tail pipe adapter thing that I was thinking of which allows you to use any wide band sensor for tail pipe AFR measurements. Some of the tips on the NSX exhaust system that really flare out wide may render the adapter ineffective.

If you are absolutely 100% confident that the valve timing is not an issue then I would check the base ignition timing as per the service manual. You can get tail pipe adapters for O2 sensors which allow you to sample on the go with a wide band sensor. Doing that might give you some idea as...

Check the pressure to rule it out; but, sad to say it is probably time to revisit the valve timing.

Can't answer that question because we do not know what the $ value of the premium is. Price out the cost of a used S2000 ABS and the wiring harness required to integrate the S2000 ABS. Add $1000 - $2000 for sundries. If the price premium exceeds that value then the premium is not worth it...

You are mistaken; but, effectively you are correct. Acura does list the suction screen separately. The part number is 1751-SL0-000 and the MSRP is around $65 US$. That has to be the world's most expensive piece of plastic screen and I expect that they don't sell too many. If you hurry...

You are correct about the air injection system which arrived with the 2000 model year. However, the air injection system only operates for a very short period of time after start up. Its purpose is to add O2 into the exhaust stream to mix with unburnt HC and bring the catalytic converters up...
