I’ve been at this problem for months. Car is at a lack of power when accelerating. And the exhaust sputtering idle but only one of the tips. The air coming from the exhaust is like thudding. I’ve changed spark plugs and ignition coils but it still happens. Could it be something with the exhaust system itself?

Did you accidentally swap coils on drivers side?

sorry I don’t understand?

Right catalytic converter. Suspecting it could be this?

^^^ 1st thing I thought of, how many miles?
Cats aren't hard to do, just hard to get to, you'll need several socket extensions, Liquid Wrench and maybe a cheater bar for leverage. To inspect remove 3 upper fasteners and drop so you view with a flashlight and small mirror. Gl!

147k miles. many of my friends told me it’s my cats. I just have been hesitant to order the test pipes because they are $250 and what if they don’t solve the problem yk.

Here's an idea- drop the top, inspect. If there's a brown or grey powdery buildup and you can't see the little squares they're clogged. If not, move on. At that point you remove completely, get the biggest screwdriver you have and a hammer. Either remove 1" off the top or gut completely. Reinstall. 0 cost, just time. It'll likely throw a CEL for cat efficiency so look up the O2 no fouler hack.

One drivers side, cylinder plugs can be swapped pretty easily.

Test pipes will need a tune or anti foulers. I would check wiring first

Deo.z33

aren’t they interchangeable. I have all new plugs.

Keep telling yourself that. Three and five get mixed up all the time

ok I will look at them today after work to make sure I put them in the right place. Also it’s a cylinder 2 misfire.

then that prob isnt the issue. i would swap coil packs on 2 and 4, see if the issue follows it
