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.

Sounds like petrol starvation - the pump may be in need of replacement.

1990 Mazda Miata!Ok so I asked this question the other day and here is where I am at now. Car starts right up but idle is low and press the accelerator and the rpms go up really slow. I tried to test


pull one plug wire at a time, observe engine hesitation to this if one or more cyl is defective you will notice no change in the engine you may have a faulty coil.

How reset check engine light


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.

Will 1992 miata side mirrors fit exactly on a 1996 miata


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.

I have a 1999 Mazda 626 5 speed and my rpms seem to always be high weather I'm driving n town, 4th gear 30 mph 2100 rpm, or on the highway 5th gear 70 mph and rpms at 3100. This I'm sure is killing my gas...


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

Is it normal for my 91 miata reads 3900 rpms going 70mph?


It is pretty close, but doing the math....
3900 rpms 5th gear .814 diff gear 4.3 tire rpm = 1114
stock 91 tire size is 185/60-14 circumference = 71.31 inches inches/min=79457 mi/min=1.254 mi/hr=75.23
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, Lars

2000 Mazda MX-5 1.8i intermittent misfire problem. (It's not a Miata but the website didn't have an option for a normal MX5!) Sometimes the car starts with what sounds like only 2 cylinders firing - it...


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.

91 miata mx-5 cuts out at 2200 rpms- cant smog- check eng. lite isn't on


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.
