    Hey I'm back guys unfortunately so I woke up this morning and I started driving and when I would accelerate my RPMs would bounce back and forth and would make a burping sound from the exhaust. I thought it was my filter and I changed it but if it's nothing I feel a little bit underpowered. But when I accelerate it basically just rattles and RPMs just bounce. No engine lights or codes. I would appreciate any help already read like 20 forums and found nothing. Maybe ECM or my pedal sensor but both replaced in the last two years.
     
    Steel Dragon Thanks this.

    I change my fuel filter I will check my air filters next. Do you think you could be my oil filter?

    There's been a ton of threads on here lately about reman N14 injectors being junk out of the box. Faulty injector wiring could be another possibility if it wasn't replaced.

    I'm just spitballing ideas. Your issue could be completely unrelated to injectors.

    It could be several things,bad cam sensor,tps,wiring.
    Will it clear up on cruise control?
