misfiring
The car is not throwing any codes, on the dash nor readable to code readers. but this afternoon right before i turned into my neighborhood as i was slowly accelerating the car felt like it misfired like crazy. it would not accelerate. after i let off the gas it went away and i could speed up again. this is the first its ever happened. 2010 with 63k miles. just got tuned by uprev about a week ago. also have injen intakes, FI HFC and topspeed catback. any ideas on where to begin? flashing the ecu back to stock perhaps?
