That's probably the problem the broken wires. The 02 sensors send a rich/lean signal to the ecm. If they aren't working right, a lean or rich situation will occur. Best to get the wires fixed. If the wires broke off at the sensor, need to replace it.

1992 toyota 22re fluids out and puts out a lot of fume out the exhast


Floods out.Multiple causes.How does it run when warmed up?Still stink?
Check injectors: Run the engine up to 3,000 RPM and turn off the key,while flooring the gas pedal.If engine still runs,the injector(s) are stuck open.
Also check for a vacuum leak-that will cause the engine to run very rich.
Also may be an open circuit in the temp sensor(computer side).The engine may think it's very cold and richen up the mixture.

How do i tell if my 1989 toyota sr5 4x4 4 cylinder is a 22r or a 22re, and what is the difference please.


If it has a carb it's a 22r, if it has a throttle body (fuel infection) it is a 22re.

92 pickup 22Re engine, runs great when cold but after heating up engine stalls and with no acelleration, and hesitation. After cooling off runs fine


Almost certainly a faulty cam sensor. This sensor suffers over time with the repetitive effect of getting hot and then cold along with the engine. The cam sensor determines when cylinder 1 is at compression TDC and this timing dictates the fuel injection cycle on the engine. If the cam sensor fails to report signals then the ECU fails to inject fuel appropriately and the engine stalls. Many times as the cam sensor gets hot it expands and any discontinuity becomes apparent. As soon as it cools down the cam becomes functional again.

My 89 toyota pickup 22re fuel injected serges when idling when its warmed up


The Idle Air Control Valve (IACV) may need cleaning or replacement.

This valve lets air bypass the throttle plate so that the engine can idle. The more air, the faster the idle. If this valve is sticky, the computer may have a hard time regulating the idle properly and may surge.

My 1989 toyota Pickup feels like it stutters from speeds 45-65 randomly... Check engine light pops on for a second then turns off. It has a 22RE engine in it and is fuel injected.


If I were you, I would rather go in for a diagnosis (scan) if my car is OBD I compliant.

But you could take a look at the fuel pump or see that the fuel system generally is okay.

Good luck.

1988 toyota 22re truck will crank and run perfect until you turn the engine off then it takes about a hour before it starts again engine just turns over.


First step, see what is missing when it wont start, fuel, or spark. Is it carburated? or fuel injected. (22re should be injected.)

Cold idle stays on too long


Has it always behaved the same? It has sensors that detect engine temp, outside temp, humidity and altitude to give you the perfect fuel air mixture for the conditions. 1300 to 1500 rpm is not unusual for cold engine warm up. You could have a bad sensor, but the codes should have revealed that problem. 10 minute warm up is not outside the norm. at idle, but 7 miles driving should make it happen a little sooner. As for the the stick moving when you "get on it", that is normal engine "torque", your engine mounts give just a bit to allow movement and to keep that "torque" from being transferred to the body/framework of the vehicle. You have hard rubber mounts. As they "fatigue" you will notice this movement increasing slightly.
