Drained the old gas from the gas tank and refilled it with new, also replaced the gas filter and charged up the battery.

Notice how your headlights are protected under the hood by a suspiciously large rubber cover? Miatas hate humidity and condensation, from head to toe, including the headlights. I lost a headlight, was pulled over by a state trooper who told me to change it, and tested the brights all in one night. Of course, the brights worked, because they are actuated from a different circuit on the wiring harness that connects to the headlight through that massive rubber seal. If any amount of humidity or condensation has occurred, especially during a weather change, I cannot stress that enough, the first thing to fail is the normal headlight setting. I was already going to switch over to high-intensity bulbs, so I had a good excuse to crack open the headlight assembly (otherwise I wouldn't dare--Miata headlights are nearly impossible to change with a large pair of hands). I separated the old bulbs from their wires and proceeded to clean the connectors of the wires with an approved electrical connection cleaning solution (go to AutoZone). I then applied the conducting gel to the bulb to avoid corrosion and secure against future problems with condensation and was good to go. Make sure to give yourself many many hours to decipher the bulb assembly, as it was designed by someone whose sole intent is to make the job 150 times more difficult. Otherwise, cleaning the wiring assembly is a cinch.

On my 1999 Miata I had the same thing happen. I found that the rear brakes needed adjusted.

It is Supposed to Be on the Left of the Sterring Wheel Under the Dash Panel. Really hard to see though. Please Rate My Response! Thanks!

The thermostats on Mazdas are notorious for kicking out and causing the fans to either not initiate or go on without effective results. My Protege went through 3 before I got my Miata, and I learned how to change the thermostat when it went out the first time. Hopefully, there won't be a second time, but whenever the car overheats and I notice the fans don't come one, I always assume it's the thermostat, and that's always the cause. If you don't want to fix it yourself, take it to a dealer, they're very accustomed to changing thermostats in Mazdas, believe me.

what should i be getting for gas milage on a 1999 miata?

possible blown head gasket

check the fuse first if the fuse is good and both head lights won't go down check if the head light switch in the middle of the dash is good

did you ask the dealer if the car an an emissions recall for this problem

I found one on e-bay.  1999 miata repair manual on cd. Look for speedracer, user name (wrench). It's a auction item so it will take a few days to get to you. I paid about 20.00 + shipping.
Good luck Duane  

when the car is cold, fill the radiator, start the car. Leave it running with the radiator cap off until the thermostat opens. If it opens the fluid in the radiator will be circulated by the water pump and the electric fan will turn on and cool the radiator. If not, the engine will overheat because either the thermostat is not opening or if the fan doesn't come on, the fan sensor is probably at fault, or both. If there is a noise and fluid leak, the problem could be the water pump. If there is no fluid leak, the problem is likely the thermostat or the fan sensor.

you are showing the classic symptoms of a failed coil pack. I think you can get one for about $230 from rosenthal mazda (finishline performance)

not solved the problem yet but when i do i will let you know but it might cost you!!!!!!!!

This is either a problem with one or both of your airbags or the airbag connector located at the back of the glovebox has been disconnected for some reason. (ie. to prevent airbag opening when installing baby seat) (1999 miata does not have a baby seat airbag disabling sensor).

You should get your car inspected at your local mazda service to check if this is a wiring (plug disconnected) issue or one of your airbags is malfunctioning and needs to be replaced.

Flashing airbag light could indicate that either one of the airbags or both have a problem. Disconnecting the passenger's airbag has the same effect.

Warning! Do NOT attempt to do any kind of airbag/airbag wiring related repair yourself. Airbag problems should be addressed ONLY by certified technicians at your local Mazda service. (Airbag fixing requires for example that the car battery is disconnected, you MUST NOT attempt anything with the car battery connected).


Hope this helps.

Question edited for clarity. Question moved to model category. Yes, you are correct, disconnecting the fuse box has broken the pairing between the key and the immobilizer system. Did you remove the main connection plugs to the fuse box? My thought is that those connectors have never been removed since the car was built and breaking a remaking the connection, you might have some connections that as not as good as they should be. Pull the connectors again and give them a good spray with electrical contact cleaner (that is NOT WD40). Then reconnect. There is various ideas on resetting the Immobilizer here. https://www.google.com/search?q=mazda+miata+immobilizer+system+reset Or a Mobile Auto Locksmith https://www.google.com/search?q=mobile+auto+locksmith+near+me Just for fun, here are the Fuse Box locations and diagrams. They have changed over the years, and as you didn't state the year, here is all of them.

The engine number should be at the back of the engine on the right hand side on a 1.6 liter engine and on the left hand side on 1.8 liter engine. Do expect it to be hard to read. You can also check the right hand side door frame for car details like VIN and engine number.

Question edited for clarity and to remove phone number. This site gets 11 million views a year and some would love to put you on a sales cold calling or India scamming list.

find a good local mechanic or dealer . we only know stuff about things we have owner and fixed for our self

You're supposed to take note of what wires go where as well as the length of each prior to removal, or better yet, replace them one by one. If you didn't do that, then you need the firing order diagram, which I am providing below....
