First disconnect the map sensor which is on the intake pipe and then disconnect the intake pipe from the throttle body. I usually use two cans of chemtool in the sprayer. Have a helper start the car and his task will be to keep the car from stalling out. The engine should start without a problem. Spray the chemtool directly into the throttle body (don't touch the butterfly valve, you can damage the servo). I spread out the spray time into 4 parts so the cats could get a break to cool down. Make sure that the space you are doing this in is well ventilated. Turn off the car and reconnect the sensor and intake pipe.
Disconnect the PCV hose on the intake piping closest to the air filter and spray chemtool into the pipe nipple. By doing this you can clean the oil out of the piping and intercooler.
