Helllo,
I am having issues with my car almost stalling when my RPM range gets between 3000 and 4000 rpms. I feel it most when taking off in 1st gear or driving in 2nd gear. The drop is a violent "almost" stallout. When I pull up to traffic lights, the rpms dip to an almost stall, or the car completely stalls. If I'm driving at highway speeds, I can get it to almost die by stomping on the gas pedal. It's almost like my car is choking to death. I have NO check engine light. I am positive that it works. I have already changed the fuel pump, fuel filter, plugs and wires. What else could possible be wrong? I am desperate for help.

Thank you.

This does sound like a fuel issue but if you changed the pump then we can assume that is okay. However, here is a guide that will help with this issue in more general terms. It will get us started on this issue.

I would suggest we check the fuel pressure just to be sure it is okay.

Lastly this could be a restricted exhaust so we need to test the converter and find out if it is plugged.

Below you will find the process on how to replace the converter as I suspect this is the issue.

Once we run through all this stuff we will have a better idea what the issue is. Please let us know what you find with this and we can go from there. Thanks
