I have a 2000 Chevy blazer with the 4.3l vortex engine it has 155k miles 4 x4 and has the abs and service engine light on I don't have codes not every time but frequently on take off the truck seems to just lose the power to accelerate it just studders and takes a few seconds to gain power almost like you put it in 3rd or 4th gear and are trying to take off... I don't think it's a transmission problem because it is automatic and does not require a downshift to correct it's self .... Hope I explained it well enough any advice on where to start trouble shooting would be greatly appreciated. Thanks in advance

It's in limp mode. Your Blazer needs a diagnostic scan to tell you what's causing it.
I would take it to your local auto parts store and get the codes pulled. It could be any number of things.
Once you have the codes you can really start to narrow down the problem. Most places will scan your codes for free.
