It's common that you get a lot of carbon build up at the base of the throttle body. Give it a good spray cleaning with injector cleaner and dry it with a hair dryer. If you find it still to dirty, you can try it again with a second can or if you can try using Sea Foam that you can buy at an auto parts store like Auto Zone. The Sea foam will clean out the carbon but also create a lot of smoke.
When i say lot's of smoke, just do a search on You Tube for Sea Foam. Good luck and hope this helps.

Yes the problem is effecting the emissions controls. Sounds like the timing if off. Take the vehicle to you local Auto Parts Store and most will scan the ECU for fault codes. This code will help you to figure out the problem.

CODE PO455 EVAPORATIVE EMISSION CONTROL SYSTEM LEAK DETECTED.POSSIBLE CAUSE - CANISTER VENT SOLENOID STUCK OPEN OR.FUEL TANK PRESSURE SENSOR HAS FAILED MECHANICALLY.OR BAD FUEL CAP. CODE PO1400 -DIFFERENTIAL PRESSURE FEED BACK EGR SENSOR CIRCUIT LOW VOLTAGE DETECTED.POSSIBLE CAUSE -DPF EGR SIGNAL CIRCUIT SHORTED TO GROUND OR DPF EGR SIGNAL VREF CIRCUIT OPEN OR DPF EGR SENSOR IS DAMAGED OR HAS FAILED.I WOULD HAVE GARAGE OR DEALERSHIP TO USE THEIR DIAGNOSTIC EQUIPMENT TO CHECK OUT YOUR EMISSION CONTROL SYSTEM.AND EGR VALVE BECAUSE PARTS IS TOO EXPENSIVE TO BUY.IF YOU DONT NEED THEM.SEE YOU CAN REPLACE THE DPF EGR SENSOR AND THE CANISTER VENT SOLENOID.BUT IT COULD BE A LEAKING GAS CAP OR SOMETHING ELSE.SO LET GARAGE CHECK IT OUT.TO BE ON SAFE SIDE.NOW YOU CAN BUY THOSE 2 SENSORS AND IT COULD FIX YOUR RIDE.I KNOW MONEY IS TIGHT ECONOMY IS IN BAD SHAPE.

The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light is turned on the computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible faults that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.
