Toyota Rav 4 1997 .Check engine comes on .Codes are P0301,302,303,304116 . What to do.

The engine coolant temperature is high. Your other Codes are for missing cylinders on cylinder 1,2,3,and 4. Get the Codes cleared and start over. Changing the plugs and wires,etc could have generated the missing cylinder Codes.

Check your engine for an IDLE SPEED CONTROL SOLENOID, which may be in the intake. Or a fuel pressure regulator.

A lot of times people work on the spark side and forget the fuel injectors. They can cause a miss.

Have had a surging up and down when idling, and now just a low idle, to the point of stalling at traffic lights. and also curious why ' check engine light hasn't come on when these...

Have you gotten good at driving with all three pedals?

I can think of two things that can cause this.

First, you make have a leak in your vacuum system. If your car just started doing this out of the blue, this is probably.

Second, if it has always done this, you can adjust the idle RPM speed by adjust the idle RPM control screw. This is located on top of the intake manifold right next to the end of where the large air hose goes on. There will be hole with a screw or a black circle cap that comes off with a screw underneath. Clockwise increases RPM at idle, Counterclockwise decreases RPM at idle.

Good luck!

100 degrees is the normal operating temperature for the motor. If it goes higher than that, the thermostate needs to be replaced. The temperature will be higher on the highway because the engine is producing more heat energy due to the higher load on the motor. Diesels idle cooler and the engine will cool down at idle or lower speeds. That is why it is best not to idle your car for long periods of time because this will cause deposits in the engine and glaze the cylinders. The engine is working normal from what you described and there is no reason to worry. I hope this helped.

Starts goes to 1500 rpm then stalls

Check engine light? I would check the EGR valve and PDFE senor to make sure its not stuck open since this controls idle speed. If it is stuck slightly open car will rev then stall motor does not know idle speed when open. Valve should be closed only time it opens is when your driving down the road.

1996 ford bronco 5.8 litre, auto, engine idle has

Do you have a check engine light on? First thing I would do is unplug the IAC motor when the engine is warm. If the idle speed doesn't change you have a vacuum leak or a bad IAC motor. If the idle speed goes down you might have a bad TPS or IAC

Would an idle control valve cause a car not to accelerate?

no, idle air control valve is literally to control your idle speed.
what happen when you press on gas? car shakes, RPM goes up, or engine just bogs down?
