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.

SOURCE: my check engine light went on & i noticed i got sluggish and was running 4000 rpms at 50 mph

Hi there:
When the light comes on, one or more diagnostic trouble codes (DTC) are stored in the engine control module. These DTCs remain even if the light goes out. To address a Check Engine Light problem, the DTCs are retrieved and the appropriate troubleshooting information is followed in order to determine the problem.

The Four Most Common Check Engine Light Scenarios and What to Do:
* The Check Engine Light turns on and off or flickers.
If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.

* The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

* The Check Engine Light illuminates, stays on, and there are performance problems.
This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.

* The Check Engine Light light comes on and blinks in a steady pattern while driving.
Don't confuse this steady pulsing of the Check Engine Light light (usually one or more flashes per second) with a flicker (see above). The Check Engine Light may stay on steadily or it may flash when the vehicle is accelerated. This is very serious. There is a severe failure of the emission control system that is causing the engine to misfire to the point that the catalytic converter is damaged each time the Check Engine Light flashes. It may mean that the catalytic converter is overheating to the point that it will glow red or, in extreme cases, start a fire on the underside of the vehicle. Immediately pull over to a safe place and have your vehicle towed to an automotive diagnostician for repair. Vehicles can be severely damaged and even destroyed by fire if this condition is ignored for too long.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Why 94 ranger 4.0 rpms 2200 take breather off rev up 2 times drops to 1700 1800 at 55 60 for a while then goes back to 2200 no engine light ?


The idle air control motor may be defective/sticky. The computer gives it a command but doesn't realize the motor is not following the command and therefore no check engine light. You can remove the IAC and try to clean it with carb spray

Idle goes up and down and when the car starts it runs at 4000 rpms.


Hi thi may be a vacum leak in one of the tiny hoses or lines at the engine ,if you dont have a vacum gage you can run a simple test by gently spay some carb cleaner spray close to the lines and air hoses with the engine runing, if you notice the rpms going high there is the problem.
