New to the forum and looking for a little help. I have a 2009 Nissan Versa SL 1.8l AT. I have been getting a P0102 code. I have replaced the MAF sensor, air cleaner and checked all the connections and wiring twice but I keep getting the same code.The engine has no power and misses. The converter, ignition coils, plugs, o2 sensors have been also been replaced. The fuel system flush by Nissan and radiator flushed and new antifreeze put in. The symptoms only happen when the air temperature is above 80 degrees and the engine temperature reaches normal operating temp. All parts are OEM from Nissan. The car has 99,000 miles. I'm at a loss on what's causing the problem. Any help on how to correct this problem would be appreciated. I am retired and on a limited budget so buying another car is out of the question.
