On the weekend, I changed the spark plugs on my 160sr, as hadn't done so in 5 years. Its a low mileage car. As its quite involved, decided to clean the throttle body with carb cleaner. I unplugged the throttle body, which is the WRONG thing to do, as you have to either calibrate throttle body afterwards with a scan tool (even worse a jdm scan tool as found out mine is an import), or disconnect battery for a hard re set. Learned this the painful way. Anyway, throttle body looked very clean. Stuffed a micro fibre cloth in one end, and sprayed carb cleaner in other end. Alternated, until id used up whole can. Was amazed at the amount of black dirt/carbon that came out, bearing in mind it looked clean to begin with. Old spark plugs were clean, just brown deposits on the ends. The result of doing both is pretty amazing. Car is a lot more responsive. Its much easier accelerating, especially uphills. Really pleased with the outcome. Thought id share, to possibly help someone else. Remember to do throttle body in situ (in retrospect can do, and better than horror of going through a manual or scan re calibration or hard re set).
