    Vehicle vibrates when in drive while stopped at a stoplight. Vibration stops if vehicle is placed in neutral or park

    Vibrating noise coming from engine while sitting at light. Stops if I hit the gas and hold the brake at the same time. I just had the engine/transmission mounts replaced and this did not solve the problem!

    2005 Trailblazer: For the past 1 ½ years it has made a loud vibrating noise that no one has been able to identify. It is not a valve and apparently not the motor mounts. When I come to a stop and the engine is engaged, it loudly vibrates. When I put it in neutral or park, it quiets down. It seems worse if I am on even a slight incline. Neither our mechanic or the dealership have figured out what it is. The dealership would LOVE to figure it out by fixing everything that isn't broken first.

    I experienced this problem. Had a dealership look at it several times and told me I was crazy. Basically, when sitting at idle while in drive the engine would rattle as if a rough idle. I started taking my vehicles to a smaller repair shop. They found that my Trailblazer was 25 computer updates behind and that after updating it corrected the problem.

    Rough vibration when in drive at a stop light. Once in neutral it's not as rough

    Vibration seems to be worse in cold weather while the engine is still cold.

    My trailblazer has a rough idle when at a stop light. It even turns off completely sometimes when in drive. Putting it in neutral helps a lot. My dad is a mechanic and he is even stumped.

    Check engine light would come on for a while then go off. It finally stayed on all the time. The engine vibrates when idling in gear, but no vibration at all when I put it in park or neutral. The vibration was worse when the a/c was on. I replaced the a/c idler pully but still vibrates. No driving issues and rpms arent affected. Took it to autozone to let them diagnose it but they couldnt get a reading. I've had a few people tell me it could be the 02 sensors but I wanted to get more feedback before I try to replace it.
