When driving the car will just stop accelerating and idle real rough. There's a wrench light that flashes on the dash and if its on, you cant accelerate any more until the car is turned off and restarted. It idles fine until you get above 4000 rpms and then it kicks out. I changed the air filter and cleaned the throttle body and plate. Any advice?
Do you
have the same problem?

Scan for codes and check fuel pressure first. Auto parts do for free

This vehicle has whats called ""fly by wire". The wrench icon you describe is the maintence light, HOWEVER, it will flash when a component fails. Ive dug this up upon some research. Ive had a similar occurance in our shop- the wrench was flashing, but no engine codes. Try this. (In my case, I found a faulty throttlebody)

1. The code indicates an issue with the throttle body or the throttle body circuits.

2. Before further diagnosis, inspect throttle body for signs of sludge, buildup, debris, that may obstruct the throttle plate. Clean and retest if necessary.

3. If no obstructions or contamination are found, monitor the Throttle Position (TP) sensor 1 and TP sensor 2 voltage readings on the scan data, while sweeping throttle open and closed. Voltages should smoothly sweep up and down together. Note: TP2 starts low, and goes high as the throttle opens, and TP1 starts high, and goes down as the throttle opens. If either one shows dead spots, or spikes, while sweeping, replace the Throttle Position (TP) sensor.

4. Wiggle test the throttle body connectors, and the wiring harness from the throttle body to the PCM to check for intermittent connector or wiring harness problems.

5. Access mode $06 through the generic functions of the scan tool and note the PCM misfire monitors through Monitor Identification (MID)s A2-A9 TID $0B and $0C to see if the measured value of any cylinder is showing detected misfire activity. If any MID/TID combination is showing misfire count or value of something other than 0, check the spark output of the Coil-On-Plug (COP) unit of that cylinder and replace the COP unit as needed. Cylinder #1 is represented by MID A2, cylinder #2 is A3, etc.
