2003 Hyundai Sonata makes continuous pop...pop...pop noise when accelerate

2003 Hyundai Sonata, 70K…engine makes a continuous pop…pop…pop noise during acceleration. So far have installed new crankshaft sensor, coil pack, plugs and wires. Any other possible suggestions??

Positively The Engine ? Will It Do It In Neutral, Car Stopped ?
It’s Definitely A Pop And Not A Knock Or Clunk ?
Can You Think Of Something That Would Produce A Similar Sound To Give Us An Idea ?


Definitely a pop…during acceleration it’s very steady…in neutral, it will pop after revving the engine pretty high. Won’t do it while idling.

Loud pop like a backfire or a softer pop? Did you have any work done on the car recently? How many miles on it? Are there any warning lights on (like check engine light)?
