SOURCE: limp home mode
You need to scan for engine trouble codes. Most parts stores will do this for free, and tell you what they mean and make recommendations on what to do. The 'limp mode' kicks in to prevent damage to the vehicle when the computer gets data that something is wrong.. When you shut it off, it's temporarily reset, but then the cars computer is signaling there is still a problem, and it goes back into limp mode. If you have any questions after getting the codes 'read' , post questions and code #;s here for help. Good luck.

mo me it sounds like low fuel volume i would check my lift pump

try to remove filter and pump out fuel from the tank. the gunk you loosened with "mechanic in a bottle" goes to filter then when ENGINE IS SHUT OFF GUNK SETTLES BACK IN LINE. NEED TO PUMP IT OUT TO SOLVE PROBLEM

You need to have the codes checked. The injectors in your engine have an issue where they either bypass fuel back to the tank or crack the body and fuel goes into the oil pan.
The warranty period goes to 200k miles, sorry I don't remember how many years, I think it was 7 years.
If you had a smoke problem before you used the kleaner you already have an injector problem.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- No throttle response
Possible Causes
- Harness or connector (The TP sensor circuit is open or shorted.)
- Electric Throttle Control Actuator (or Throttle Body Motor)
- Accelerator Pedal Position Sensor (APP)
P0220 Description
Electric Throttle Control Actuator consists of throttle control motor,
throttle position (TP)sensor, etc. The throttle position sensor responds
to the throttle valve movement.
The throttle position sensor
has the two sensors. These sensors are a kind of potentiometers which
transform the throttle valve position into output voltage, and emit the
voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
When is the code detected?
An unexpected voltage from the TP sensor is sent to ECM.
