Rough idle

[RamTrxUSA]

I managed to fix it a bit. The exhaust would sound like it’s chugging.

Ever since I replaced the spark plugs, belts, all accessory pulleys and tensioner it has improved.

But after idling for a bit you’ll hear a valve terrain kind of sound.

Slight acceleration while parked is how I’m able to replicate it to happen more and you can hear it struggle/misfire occur.

The misfires are mostly happening in cylinder number 2. This was 2mins of recording till my phone died. 10 misfires.

Any idea what could be the issue. No cel /engine light.

Wrong spark plugs maybe?

I'd consider fuel delivery issue regarding misfire. Do you think what you hear (not misfire code) could be exhaust or coil packs?

If you don't run a good fuel with enough detergent you could pour in a bottle of techron next fill up. Possibly have a bad or dirty injector.

Here is an updated one after a quick 30minute drive.

I noticed the misfire happen at idle or coming to a stop.

Misfires are in 2,4,6,and 8 cylinders.

Hit a total of 34 misfires for cylinder 2.

Wrong spark plugs maybe?

I thought this as well but it’s only happening on the passenger side for the most part. I’m thinking a head gasket?
