when leaving work with temps below 0 I started my trailblazer and let it sit for say 2 min ( I used my remote start so it was running for a little bit before I got to it.) got in and checked the gauges as usual when its below 0 and they looked fine. backed out and heard/felt a bang. thought I might have hit the car next to me but I was 5 feet away from it. figured the noise was ice falling off from underneath that I ran over.
got to the first red light I felt a vibration in the gas peddle, which is normal in the cold when I start driving at first. gauges still fine.
got to another light about a mile down the road, the vibration in the gas peddle got my attention and I turned down my heat and heard this awful noise coming from the engine. gauges still normal.
this is not my video or car but this is the noise it makes. however when mine makes this noise it does not seem to be as consistent in timing, it's more random. it is also louder, I got home and my parents came outside to see what in the world was happening.

while driving I noticed at certain rpms (low ones seeing as how I didn't want to go higher) the noise would sometimes slow and stop then return as I left off the gas. no change in engine performance otherwise. exhaust sounds the same.
here are the things that have already been replaced / cleaned in the engine:
replaced:
belt tensioner pulley
belt tensioner (bearing on the other side)
went through 3 belts
6 sparks plugs (bosch platinum 4 pin)
oil cooler lines
power steering lines
air intake (by choice, it gives better gas millage)
cleaned:
throttle body
air intake
fuel injectors ( by local shop )
115,000 miles
the video says its a bad rod bearing but I like to believe its not haha.
any ideas?
