I recently noticed my car sometimes "choke" while driving. It just started doing it last week Like I'm cruising at 70 MPH and I feel the engine sometimes kind of choke. RPM won't change, but it's like a having misfires. It does not happen a ton but it clearly does enough so I feel it and it seems kinda buggy.

I am getting close to 45 000 miles and they are still original spark plugs, could it be it?

Anyone experienced somethin similar?

 

It's claimed that the plugs are good for 100K. I don't know if that's true or not.

Do you have a MIL (CEL)? Im guess you may and if you do it's code P0300.

Its possible you may need to check your air filter. It appears you have a "K&N Drop in" So pull it out see if its clogged or gunked up or something. Its probably a good idea to swap out your plugs anyway.
