Hey gang... I got a problem... I drove my truck today to work. It ran fine enough until mid morning.... then when it was warmed up and fine it started doing this.... I got to a light and as I was slowing down it began to vibrate and shake. Not really violently, but enough to make me think something is for sure up... at idle it didn't shake quite as bad but idled like garbage. When I hit the gas when it turned green it accelerated really slowly and shook pretty good up until about 8mph.... it would drive and accel slowly up until about 35-40mph... after that it drove fine, shifted perfect and was going on the freeway fine. It would run fine until I slowed down under 10mph then it gets the shakes again. Again repeat the struggle to accelerate if I need to speed up.... another thing to note, my exhaust is not exactly quiet, but it's louder now for sure and it has like it's got some weird go kart thing going on when I gas it. At idle it doesn't do that but it's still way louder then normal. Also on acceleration sometimes it would for a split second right when the gas was hit make a sound like a diesel semi truck (like when they idle) up in the engine... I am stumped where to start to be honest... any ideas to check for because this is new to me. Thanks!
