wha t code number battery will fit my 1998 mx5 special most batteries are too high and are above the level of the boot floor

California has a law that Mazda guarantees the timing belt will last 105,000. I drove my 1999 Miata that long before I replaced it. Mazda ia a non interactive motor which means that if the belt breaks the car stalls and won't go anywhere. No damage to engine if it breaks.

Thanks for using FixYa and welcome to the site. You can use 89, but you are better off using 92.

Hi this sounds very messy if somebody has made a mess of things the only way to check it out is to get it to a reputable garage and get it checked over ,did you have the head pressure tested as a common fault with these cars is internal cracking of the head which can often look like a head gasket failure the only solution then is a complete new head good luck with this

hi you will need a timing belt and tensioners these may come as a kit ask your dealer or supplier
and a thermostat housing gasket and antifreeze/coolant and possibly a cam cover gasket depending on condition of your old one they are rubber and you can normally re use them at least once but if there is any sign of leaking before you start change it good luck

Stock timing on this engine is 10 degrees BTDC at idle (approx 800RPM).

This is from a na (pre - 98), but you can check to see if it is the same.

All batteries have to have a + and - or "plus" and "minus" or something.
But all you need to do is take a test light, and ground the clip on any bare metal, like port of the engine. They which ever terminal lights the probe has to be the plus. The engine and all chassis metal is always the negative. I suggest you then get those red and black felt anti corrosion pads for the terminals so that you will know next time.

P0031 Oxagen senser heater circuit. The heater circuit can be checked with a test light connected to ground. ( a tast light is an ice pick looking tool with a clear handle with a 12 volt bulb inside and a ware with a clip to connect to grond, the light will light as the tip is touched to anything powered up with 12 volts and sometimes a little more and a wholde lot less) Find the oxagen sensers ( thier screwed into the exhaust pipes) Disconnect the electrial connectors and connect the test light to ground, with the key on test the wires in the plug connect ed the vehical. one of them should light the light, if it does reconect it and test the rest of the sensers, recalling which wire was live. ( most are white or grey but they vary some. If all the sensers have power it's not the power but the senser failed. with an ohm meter test the senser for the wire that was hot to the other wire that is the same color if the sneser is open ( no circuit ) you have found the bad senser. If you can't find power going to any of the sensers. Check the fuse boxes for blown fuses ( check them all with a test light) If you find a blown fuse replace it but go back to the wiring tjat connects to the sensers and you'll find someplace where the wire melted to the exhaust pipes and shorted out, blowing the fuse. The sensers short out too but not very often.

Thank is how you do it. The answer is yes. There are bolts you will also have to remove that attaches to the motor.

Hi,

Open the door of your Miata and locate the three screws in the door panel. The first is located in the trim plate where the door handle is. A second lies below that inside the grab handle on the door. The last one is found in the upper end of the door handle.

Remove the three retaining screws on the door with a Phillips screwdriver. Locate the three push in retainers on the panel. There is one on the face of the panel near the upper front corner and two in the rear door jam.

Lift the center of the retainers with a flat tool or small screwdriver. Pull the door panel out from the bottom. Lift the panel out of the window track and move it out far enough to access the wiring behind it.

Remove the electrical connectors for the window and door locks by unplugging them from the switches. Unplug the wires from the door speakers and remove the panel. Set it aside.

Locate the wiring connector for the mirror heater and adjustment motor. Unplug it from the wiring harness connector on the inside of the door.

Turn the mirror on your Miata sideways to reveal the two mounting bolts inside the base. Remove the bolts with a socket and ratchet. Pull the mirror off the body, fishing the wires out of the hole in the body.

Best regards.

Check your freon level, sounds like you lost it all, blown out a gasket/seal on one of the lines. use freon with UV in it and get some UV galasses from the parts house to locate your leak. Repair the leak before installing alot of freon. You might take it to a mechanic and have him pull a vacuum to find the leak instead of using that extra freon, your choice.

I would suggest taking advantage of Autozone's(or similar part store) free engine light diagnosis. They can print you off a receipt with codes and the most likely causes and fixes for the issue(s). This will give you some idea of whether you are being ripped off or not. If it doesn't seem like your mechanic is saying the same thing the code is ask for an explanation and then make a judgement of whether you are being taken advantage of. Hope things get better for you.

exhaust doesnt sound like a code, there should be more to code than cat or exhaust, the cat code is probably like cta efficencey below thrushold. this means the converter is not working, the cause maybe bad cat or bad oxygen sensors, testing may be needed to see if o2 sensors are working good. the exhaust code i dont know, never heard of exhaust code, they may be caused by the same problem, start with the cat code, have o2 sensors (oyxgen sensor) checked or if over 100,000 miles replace them. if converter is bad it a very good thing to also replace the o2 sensors with the new cat.
