Hello everyone I’m Jason I’m new here. I’ve been contemplating purchasing a 96 impala for the last few months the one I want to buy is having a power problem. The car starts and runs and drives well unless you put your foot into it. If you give the car more than half throttle the motor sounds like it’s miss firing, like the fuel cut out. Again runs well at low rpms. Any suggestions for great shops in Portland or area

Welcome! I would say if it is in good condition and the price is right get it. They are getting hard to find. The issue could be anything, low fuel pressure, wires, plugs, vacuum line ect.... Keep us posted

Hi Man !
since it's a 96 you can put a scanner on it easy like a ELM327 and torque app on Android phone and watch what is EFFed up like O2, or MAF or fuel trims...

But my guess is fuel pressure check it first thing, cuz easy to rule out.

-ALF out...

If fuel pressure is too low, check fuel pressure regulator [underhood, behind engine].

IFF your fuel pressure is good:
Check coil
Check coil driver module
Check Opti-snorkel aka Opti Vent Vacuum Harness
Check for vacuum leaks between MAF sensor & O2 sensors
