So I just replaced the plugs hoping that would f&x the problem. It didn’t! The car sputters/misfires when idling and when under load. It sounds kind of like running out Of gas but more severe. I don’t know what to do it has a new air filter. No check engine light. It seems like when it’s under load it just cuts power for a second when it sputters. Any ideas?

 

2 coil pack plugs are swapped

 

Good thought. 4 & 6 usually are the culprits.

But.... if the problem existed before pulling plugs, most likely misfire or vacuum leak. Pull the codes and look for P03xx (and other) codes. Could just be a bad coilpack, which it often times is.
