92 NSX is running well, regular service but the check engine light just came on. Any advice on what to look for?
Check Engine light
- Thread starter the hunter
- Start date
It could be lots of things but a bad O2 sensor would be most likely. Pull the code and you will know.

Thanks for the advice, shorted the connector and saw one lamp flash once and another flash 6 times. How can I convert this to the code? Thanks in advance.
Was it one long and 6 short together or 1 short, pause and the 6 short?
one long and 6 short together
Code 16 -- fuel injection

It isn't running rough, like it's missing a cylinder?

The engine does seem a bit fluffy around 2000 rpm but she drives well. Does this mean I need new injectors?
It's possibly intermittent. Clear the CEL and see what happens. If it comes back then you'll need to start measuring resistances. Measure at the ECU--that way you measure the entire circuit up to the ECU connector. If an injector was really OL there would be a dead miss that would be obvious at idle.
Re: Check Engine light- code 16
Could not clear the CEL, I ran the engine for a while and there is certainly a misfire, must be one of the injectors. I will buy a test meter. Thanks to all for helping in the diagnoistics. I assume its best to change all of the injectors? One final question, if I have to drive any distance in this condition do I risk damaging the engine?

If it failed or cloged there would be no problem driving the car. You can send the injectors to RC Engineering and have then cleaned and tested which should be much cheaper then replacing them.
I've heard good things about RCE-good idea for the injectors that are still in spec. Verify the resitance through both the harness and at the injector itself to isolate where the problem is. No sense paying for service on an injector with a bad coil, and no sense replacing a good injector that only has a faulty harness connection. Usually it is the injector though.
