it doesnt sound too good, i had a misfire issue last week but when i tightened the spark plugs it went away. i changed the oil and went full synthetic about 3 days ago. it sounds like theres a vacuum leak but the only thing that bothers me is it almost sounds like a little backfire every 20-30 seconds. if you watch the tacho you can see it will bump up and drop once in a while

Sounds fine to me? RPM surge looks ok too.

 

Any other drivability symptoms? Your intake manifold is made of polymer which doesn't absorb noise all too well. If you had an intake leak that was that noisy it would trigger a MIL or would hardly accelerate from the large amount of un-metered air

 

well im not sure how these cars drive so im not sure whats normal but say i go to neutral or push in the clutch to let it down to idle, it will drop what seems normal to 1500 rpm and then a real slow drop down to actual idle. you couldnt really hear it in the video but it did sound like a little knock or backfire at idle every once in a while. i can replace and fix whatver if wrong but idk if its wrong? lol

 

looks and sounds normal to me , HRs def don't have a smooth idle lol . you'll have a random hick up when idleing sometimes which is normal

 

well the motor blew up lol so i guess it wasnt running right. ive got the logs if anyone would like to see but they actually look alright judging by AFR

 

Did it really blow? If so how man miles on it. Covered under 60,000 mile warranty?

 

something doesn't add up. The HR is a robust motor, and for it blow up with 58k miles (peeked at your odometer briefly), it doesn't make sense..
