Re: 1999 Miata - Check Engine - Help

Pat, do this first !!!!!!!!

Check that there is NO water in the O'2 connectors. (blow out with air)
 
Go back and remove the "ground cable" from the batt. ( I don't know if
your radio needs a code to restart, but find out what it is before you
do this!)
Wait about 5 mins. and put the cable back back on.
Reset all of your radio stations :-)  and start your car. " IF " the
code comes back, then go start looking at other items to cure the
problem.

Removing the cable, lets the computers reset themselves and many times
that is all you need to do.

Good luck and I hope this helps.
