Question about 2004 Chevrolet TrailBlazer
I just got the transmission replaced on my car but now everytime I turn it on it seems like it's almost choking on the gas then if I turn on the heat and I'm at a complete stop the car will stutter for a few moments then turn off.
The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean. Make sure to clean the front and back sides of the throttle body. Also, disconnect the battery during the cleaning process to allow the computer to reset and relearn to the cleaned throttle body.

the computer may be making the transmission shift into low gear this would make it seem like the transmission is slipping

Two things here.Its either theres a bad ground from the tank to the frame or the fuel sending unit in the tank is not working properly...Give all the ground wires from the fuel pump harness up to the motor..Make sure not corroded.If all the wires are good than its the fuel sender in the tank..Hope this helps you find your problem and have a great day...

you might have an engine problem...im going thru sort of the same thing right now....it kinda makes a rumbling motion when your slowing down and feels like it wants to completely shutoff as you come to a stop...i dont really know if there is anything that can be done, try a tune up first but if that doesnt help it then just deal, it a nusance but hey at least it still runs.....

You may have an intermittent slow response on the rear O2 sensor, I'm not sure if you have a pre and post O2 sensor, off the top of my head, but I would get the system hooked up to a monitor to see if there is any pending codes (big change over from 1994 to 1995). Is it an OBDII system? As far as the stumbling, I have a 91 silverado with a 5.7L engine and it's had a very light stumble at idle since new, day one, and every sensor is on target, idle, 1000 rpm, 2000 rpms, 3000 rpms, and still has a slight stumble with all sensors within range. To this day it still has a slight stumble but it still runs great, Good luck, Gary
