Engin runs fine at idle but stalls out at high idle and wont rev up.

What causes an engine to stall at idle?
If the engine stalls while idling or driving, the engine may be running out of fuel or not receiving enough fuel pressure to keep it running. The most likely cause of this kind of stalling would be a fuel pump that is not spinning fast enough or is intermittently cutting out.

I have a spark in 2013 when my engine to shut it rev very high and therefore the revs back a bit or if I applied the brakes rev you very high

run fault codes tp check for faulty sensor. If carby adjust the idle mixture screw or check that the idle solenoid is operational and not blocking of the idle circuit.

ngine stalling and rough run issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

the motor wont rev high on choke.the motor is suppose to fire once on choke. then turn the choke off.pull the start cord and the motor should start and run.check that the throttle conrol is on full. it should run fine.

double check the spark plugs are tight as well as the wires.

check the spark plug sounds like you gotta fouled plug if that dont work get some carb cleaner and spray the carb out and check the air filter under the seat

Am not shure the kind of engin you really have but see if your stepping mottor is damage or need relpacing. that problem can happen if you have a faulty unit . it also called the step up unit or sensor, if your car have air condition is turned on and the rpm goes up and down that can be the problem , the unit can be found attached to the throttle body. just below.

I had the same issue with the same car....turned out to be my Idle Air Control Valve. The mechanic cleaned it out and so far my car runs fine. Actually, a little better than before. It wound up costing me $88.00 for the mechanic and $45.00 for the tow. Hope this helps you out.

Oh by the way, it would've cost me $475.00 to get the part replaced...
