Fuel Problem?

Asked by Aug 07, 2017 at 07:39 PM about the 2003 Chevrolet Blazer LS ZR2 4WD

Question type: Maintenance & Repair

I have a 2003 Blazer ZR 2 with a 4.3L V6. The issue
I am having with it is that when I rev the engine in
park, the RPM's won't go any higher than about
3500. Also when I drive it around, my speed is
limited to about 35 MPH. I have noticed while just
revving it in park that it seems to stutter on the way
back down to idle. I have replaced the O2 sensor
on the exhaust along with the MAF sensor to no
avail. I'm clueless on what else the issue could be.
Do I need to delve into the fuel system itself?
