oxygen sensor
I have just bought another mx5 today, it is fairly standard except for an aftermarket headers exhaust etc. I have just noticed the oxygen sensor is just sitting in the engine bay as I am guessing there was nowhere in the headers for it to go? I will get an exhaust shop to fit it.
The cars runs very well but my question is what will this be doing to the car? Running rich? running lean? Down on power? Using to much fuel?

yes it will be running rich and youll have idle issues. my suggestion is to get a bung welded in down at the collector and upgrade to a heated o2 sensor. your car will run MUCH MUCH better for it.
Trust me on this one. i did a fair bit of data logging the 02 sensor on my car and at the lights it would cool down too much and lose the signal.
also a NA mx5 runs off the 02 sensor ALL THE TIME except for two occasions-cold start and full throttle above 4500rpm.
yes thats right.....even at full throttle the car is running off the 02 sensor right up to about 4500 or so rpm.
eated o2 all the way!

you may get slightly better running and certainly if you do short trips it will help, but other than that not really. you just have to keep the sensor in its correct operating temperature and it gets tto cold down by the gearbox and goes dead at idle and sometimes even cruise.
