ive tried cleaning it once..and i was dumb enough not to read instruction for cleaning it..after cleaning it..i waited for 20min(i didnt know i was supposed to waited until it was completely dry inside out..) and install it..and there it goes..maf sensor gone faulty..new maf sensor installed..,cost me hundred bucks..and its was like a virus..after it goes faulty..it effect everything..2 trouble code found..injection timing control,maf, light up..and now its top overhaul..blown head gasket..not sure if the head cracked or not..
