91 miata mx-5 cuts out at 2200 rpms- cant smog- check eng. lite isn't on
91 mazda miata mx-5 cuts out around 2100-2200 RPMs. Doesn't matter if it's in gear or park. Check engine light doesn't come on so there's not any trouble codes for the on-board ECU diagnostics. Car was running fine ( though it was sitting for awhile ) untill I took it for a smog test. The air bag warning light does come on and flashes 4 times- pause -4 times, etc. Cant find or hear any vacumn leaks or worn wires/connections. Please help.

The easiest way to reset a check engine light on almost any modern car is to disconnect the battery wait five minutes and connect it back up. This will not tell you why the check engine light came on. For that you need a ODBII scanner, but if the issue was a gas cap left off and you have fixed that, then check engine the light should go off. I have found that many auto parts stores will read your car's ODBII codes for free.
The above is a good explanation of accessing the mirror but to answer your question directly, yes, they will fit. All the 90-97 mirrors are interchangeable with the exception of installing later power mirrors onto a 90-91 Miata where it wasn't a factory option. They will mount up fine but do require enlarging the center hole where the wires need to run.
check clutch for slipping condition,mayb due to worn clutch disc or a oil contaminated disc or a weak pressure plate not locking disc to flywheel therefore giving u a slipping condition and higher than normal rpms
anything is possible when it invovles cars some engines have both sensors at rear of engine it is possible for unit to fail could bee wiring issues later engines had seperate sensors on front of eng highly unlikly in this instance they wood both fail together
It is pretty close, but doing the math....
5th gear .814
diff gear 4.3
tire rpm = 1114
stock 91 tire size is 185/60-14
circumference = 71.31 inches
Completely stock, 3900 rpm gives you 75 mph. not the 70 you were claiming, but you could have smaller then stock tires (one inch less of diameter gives you 72 mph at 3900).
Hope this helps,
All MX-5's are MIATA'S. the coil pack may be bad. 3000 rpms at 20mph, sounds like the trans is slipping if it was an automatic trans. it helps when you tell EVERYTHING about the car, like what trans is has, ect.
The very first thing to do is replace the ignition wires. These were a very common problem on Miatas. Since you're taking them off, it would be a good idea to change the plugs as well. These things are really just maintenance, but one other thing to check is the condition of the intake hose. It is critical that the hose that runs between the throttle body and the airflow meter has no cracks or flaws. Sometimes they are hard to see because the hose has creases in it. It's a good idea to take the hose off and inspect it carefully. If it is broken in anyway, the airflow meter won't know how much air is entering the engine and fuel will be cut off.
