03' Silveraldo stalls when in gear and off the gas
I have a Chevy Silverado 03' 1500 2wd with the 4.8L. Within the last 4 months my truck has been stalling on me. When started and in Park or Neutral it is fine, when I put it in any "moving" gear...Drive, Reverse, 1st, 2nd, or 3rd, the voltage and rpm either drop or fluctuate up and down almost to where it stalls. When I put it in gear and start moving and then let off the gas it stalls but will start back right away. It doesn't always stall but when moving and let off the gas the rpm and voltage do go down everytime. If you have any ideas or know smething I don't....PLEASE HELP! I've changed the battery and fuel filter, it made no difference.

RE: 03' Silveraldo stalls when in gear and off the gas
I had a similar problem with my 5.3 liter truck. Turned out to be the fuel pressure regulator on the fuel rail. It is on the driver side of the rail. A small round dome with a vacume line attached. Just clips in so it is easy, although not cheap, to replace. Others I have talked to have had the same problem with the same fix.

I have a '03 Silverado 5.3L that has a new fuel pump and throttle body. It stalls when shifted into reverse or driver. It has had the codes read and all that shows up is the O2 sensor. MAF has been cleaned and is working as it should. We are kinda at a loss as to what might be the issue. I see many of you say that it could be the fuel regulator, but I am thinking that this problem is electrical. The RPMs drop to around 500 and then it dies within 3 seconds of being put into gear. If anyone could please give me some insight on this, my email is Lmccoy1101@gmail.com
Thanks in advance!
