I have a 2002 trailblazer LS, started it, no problems, idle was fine even when in drive, then when I pulled out into the street and went to accelerate, it’s like it didn’t want the gas or want to accelerate. It’s done it a couple times. Please help

OK --- new list....
Because you said that it backed up OK - then we have to suspect the only thing that changes when you choose to go forward - the transmission. --- maybe.

  1. The transmission is starting out in a higher gear than it should - might be an electrical problem with a shifting solenoid inside the transmissio.
  2. I'd start there ↑ - because i'm not there where you are and I cannot test drive it myself.

i never said anything about reverse. I back into my parking spot at home. It’s just once a day that it happens and many people have told me it’s the throttle body

The title of your post suggests that you had sputtering or misfires but you didn't state that in the body of your original post. If there was sputtering or misfires I would think the problem is most likely fule/air/spark related and not anything to do with the transmission. Even though your CEL is not lit If you have access to an OBDII code reader I would highly suggest getting your codes read because you possably have pending codes that will give you better direction what to look into. There is a possibility it could be a bad throttle body, but at $200-$400 that is a rather expensive part to shotgun replace instead of doing proper diagnostics to verify that the part is bad.

I had the same issue with my 04 trailblazer. I would hit my accelerator, nothing. I pressed the pedal again, it moved as if it never missed a step. My truck didn't throw a code that I could see. However, when I hooked it up, I pulled a code. As said previously, make sure you get it checked before you make an unnecessary purchase.
