Right now I am having problems with my car... Right now i can not go over 3500 rpms... When i reach that it starts to tach out... I ran my codes with the key in the on position and 81,82,85,84,22,33 and 95 came up. I also ran the codes with the car running and 33,94 and 44 came up. I know some of these are smog codes and i am running long tube headers but for the others, what are the specifics that i need to do to get these to go away?

Most of the codes are emissions related (KOEO 81, 82, 84, 33, KOER 94, 44). There is a EGR delete kit you can buy to remove the egr codes.

But code 22 is for the MAP which states its out if range,
85 (KOEO) Shift solenoid issue and
95 Fuel Pump Circuit Fault.

MAPs can be tested with a DVOM and a vacuum gauge. There very simple to test. Shift solenoids and be ohmed (when disconnected) but i have never worked on a vehicle with a shift solenoid issue on an OBD1 so hopefully someone else with trans experience will chime in . For the fuel pump, do some basic voltage tests.

So for the fuel pump circuit fault, there could just not be enough voltage going to the pump?

I am getting code 95 when I am running the codes on my mustang. Code 95 list as "fuel pump secondary circuit fault". What can I do to fix this?

circuit fault detected by pcm is almost always an open circuit. Get a wiring diagram, a pcm pinout, and start checking the circuit with a meter

ok thanks, i will try that

Thanks to everybody who helped me with coming out with things to check, but i got the car working fine now. I ended up being a wire that went to my starter solenoid that was on the wrong post. I called the tech support of the maker of my efi swap harness and told me a wire that went to my starter solenoid needed to be on a post that only was hot when the key was in crank position and i had it on a post that was hot all the time. So now for a tune, does anyone know of any good places in the bay area?
