Indeed it is a 2013 isx 2250, I haven't replaced tne air filter nor have I done an egr tune up. I do however change the oil every 10k miles to minimize soot build up also never idle the motor. I will consider all these things you mentioned and have my mechanic in New York work on it .. Can't thank you guys enough for helping me get to the key factors and quick response.
