My throttle stays wide open when I start the car and won't respond to the gas peddle Whats wrong

John, first make sure it is not floor mat or carpet holding gas peddle down causing throttle issue. If all looks good there, would suggest you check throttle cable for being seized, throttle body seized or return spring faulty/broke. You may want to contact a good Tech, have them diagnose and estimate repair. Check the attached links,instruction and guides, Good luck

Throttle body stuck wide open DodgeForum com

Sticking gas pedal fix Saturn Series cars and others sticky gas pedal

the throttle is wide open check to see if the spring is broke at the throttle body follow the cables one is a fuel peddle the other is for cruse both cables is hooked to the linkage on the throttle body

Assuming everything is working correctly, you may have to drive it up to 50 miles for the computer to relearn the basic perimeters.
I think you can also turn the key on, open the throttle to wide open, then close it 2 or 3 times to reset the memory in the computer.
Not sure about Jeeps.

sounds like a bad throttle position sensor or a fuel pressure regulator. also check the idle air control vavle

Throttle body position sensor (TPS), JUST locate the throttle body and you will see an electrical plug, RIGHT at the throttle butterfly, check if it's LOOSE or if there's anything WRONG with the WIRES, and go from there.
Normally, it will have like 4 wires, not sure about the color, but 1 is constant power, 1 is output signal, 1 is IDLE/Wide open throttle SIGNAL, and the LAST is ground.

Use a Voltmeter, hook the NEG-(black lead) to chassis or BATTERY NEGATIVE. The RED lead is probed into any wire to check for any voltage. ONLY perform this check when you have Ignition ON, means that you have power, but engine OFF. Do not take hours long you will drain the BATTERY.

Power wire will either be always 5V or 12V constant.
Ground will have ~0 Voltage.
OUTput signal wire will VARY as you work the throttle, start at 0.5 "ish" and 4.5V "ish at Wide open.
The idle switch signal should switch between maximum and minimum value as you work the throttle BACK and FORTH.

CHECK ONE AT A TIME.
IF NT working, look for a new part. IT's TOYOTA should not be EXPENSIVE.
FEEL FREE TO DESCRIBE what you find to me :).

timing marks off a tooth or bad vacuum leak

You can get a FREE engine scan at Autozone, Advance, and Oreilys. This will explain the engine light. Most likely you have a temperature sensor that is bad or your thermostat is stuck wide open.

I noticed you talk in KMs instead of Miles so you are probably in another country. This may mean you will need to go to a different autoparts store or garage who can scan your car. Your car may be stuck in the "cold" cycle which sets the throttle response and other driveability parts.

In a foreign country, you may not have the Pollution controls we have in the States so some of the responders may give you solutions for parts that are not on your vehicle. If you have catalytic converters, they can clog and give you some of the problems, but a cold engine usually means the coolant is circulating full blast and the thermostat and Electric cooling fan are over cooling your motor.

No, you won't do any harm in the short term, but it would be a good idea for you to put it in for a tune-up, so that this problem will be fixed properly, and the car will be 100% again. Don't forget to mention this problem when you book it in.

change fuel filter- add fuel injector cleaner to tank- drive for a while- if no improvement possibly a plugged catalytic converter

Sounds like you have faulty throttle position sensor (TPS) or TPS connection. Normally when you hit the gas the throttle plate jams open and the position change is immediately sent to the ECU which responds by extending the injection cycle to put much more fuel into the cylinders to accelerate the engine. If the TPS does not send this immediate information, the ECU relies on the mass air flow and intake air temperature sensors or Manifold absolute pressure sensors to detect and send signals. These are much slower to respond to throttle changes and so there is a time lag. If it is the TPS then a quick check is to see if you can catch the ECU out. Step on the gas very quickly when the car is idling. If the car stumbles or stalls it is because there was no response by the ECU to the sudden change in throttle and the engine was forced to run lean. The converse of this situation is that the engine often takes its time to return to idle after being at high revs.
