When I put my 2003 GMC in drive it hesitiate. But when I put it in neutral it calms down

When a vehicle is in neutral there is no load the moment you put it in gear then there is a load,If you hesitate in gear and try to accelerate and it hesitate you have a misfire,sparkplugs,sparkplug wires,If you dont have coil wire the the COP (coil on plug) either way you have a misfire

I have a 2003 GMC Envoy XL. I replaced the battery yesterday and when I started the car, the engine had a VERY rough idle, died a couple of times and then the SES light came on. I was told to drive the car...

When you disconnected the battery, the PCM (power control module) was reset to factory default. You can try driving it with several engine on/engine off cycles. Get it up to 50 mph each time so the computer can recognize the transmission operation also. Hope this helps.

My 2003 envoy shakes and vibrates when I am stopped or it at an idle. It seems to be missing and has a decrease in power when driving.

This sounds like a mifire and you may have a bad coil, have the computer scanned for codes, the codes will tell you what cylinder is misfiring, from there replace the sparkplugs and the bad coil.

You have a 4.2L inline 6 cylinder, on top of engine you'll see six coil pack's running front to back on top of the motor, disconnect harness on each one remove small bolt's pull all six coil pack's out, spark plug's will be in there.Don't worry you don't have to put the coil pack's back in the same hole.

You don't have to put the coil pack's in the same hole they came out of.
