Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
Flex fuel vehicles can develop fuel calibration issues resulting in illumination of the Check Engine Light and/or lack of power. This commonly occurs if only short trips are taken after changing fuel type from E85 to gasoline or gasoline to E85. In most cases, the fuel calibrations can be reset for gasoline using a properly equipped scan tool.
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

DexCool antifreeze formed brown gel-like sludge, first observed at radiator cap. Supposed to last 100,000 miles. Lawsuit settled for cases where engine failed. Flushed system and replaced coolant. Keep air out of system by ensuring coolant reservoir always at proper level and check radiator periodically by removing cap.
The crankshaft position sensor, ignition module, and/or powertrain control module (PCM) may fail resulting in illumination of the Check Engine Light with ignition system related fault codes stored in the PCM. Patience is necessary when dealing with this specific situation as normal diagnostic procedures are not effective. In many cases, the best option is to replace parts, one at a time until the fault is corrected.

Wires broke on side of shifter. This part will fix it. GM #13583923 or acdelco #pt3923 around 20 bucks. It has 6 wires on it but all you have to do is cut 2 wires off that you dont need. It took me about an hour to fix this.
