Sounds like a miss..

[Firestorm]

Gentlemen.

Whilst idling my vehicle seems like it is missing. This jars the Ex a little bit, seems like it does this 3 times in a row, waits about 20 seconds then repeats.

I had noticed a slightly audible hiss coming from the driver's side engine compartment. You get a really good ear full if you turn your wheels to the right and stick your head in. Sounds like it is coming from the exhaust manifold.

A friend of mine tells me that this is probably a doughnut gasket? What do you guys think? Also, would this cause that "miss"?

Engine isn't throwing codes. Any advice is welcome.

Thank you.

Sounds like you might have a vacuum leak somewhere.

Plastic underneath the wheel well on the left side is hard to remove. I nearly destroyed it last weekend while I attempted to remove a dent that I put into the left front quarter panel.

Basically then, it seems like I have this isolated? I think it has to be somewhere around the exhaust manifold? That's what it sounds like from the outside.

Thanks bud.

I'm not completely sure where things are on that motor, or I would help more. Somebody else a little more knowledgeable should chime in though.

try tightening the exhaust bolts a little...if it changes, thats it

Alright. I really appreciate you guys. I'll attempt to tighten them.
