Sign In I have a 2003 Trailblazer lately at 4,000 RPM's it feels like it doesn't get any fuel. The code came up as fuel too lean so we changed the fuel filter and pump with little results!!! Now it will not shift up from 3rd but the tranny feels fine. We also replaced the fuel pressure regulator. Any help would be awesome I am about to just trade it in I am so frustrated!!!!

Sign In Even with the parts you have already replaced I would check the fuel pressure, T kgower New User Aug 29, 2007, 2:54 PM Post #3 of 5 (2149 views) Re: 2003 Chevy Trailblazer At Witts end!!! Sign In We have checked the fuel pressure it is good the dealership had it today and think it might be the oxygen sensor, but they aren't sure.

Sign In Why are they "thinking" it's an o2 sensor when the car's computer would say so by code? Get the code read and see the results. The reading may be wrong but it leads the way as to where to go next, T kgower New User Aug 29, 2007, 4:35 PM Post #5 of 5 (2145 views) Re: 2003 Chevy Trailblazer At Witts end!!!
