Hello Everyone, i need some help i have a 04 ford mustang gt and my car has been running very bad, wasting alot of gas, i started getting all the 4 codes for the all four oxygen sensors so i took it to a shop and they told me everything is fine and it might be the PCM computer, so i ordered a new one and i had it programmed by the company i purchase well when i install it gives me a theft engine code and car will not start at all. i called the locksmith and he tried to programmed module with one key, he couldnt get to start the car. So my question to all is could it be the module and do i need to have programmed with two keys instead of one. I am thinking of going the ford dealership. i need your help.

you need two keys whenever you reprogram the pats system. Id take it to someone who is competent with pats. Like the dealer..

paid a grand for the car with a bad motor, swapped in a junkyard crown vic motor, threw a 70mm on3 kit in with all the supporting fuel/suspension mods, currently hovering around 10psi.(got bored and turned the boost controller up lol) made 410/480 on 8psi. Theres about 6k total in the entire car. I went over just about everything from the trans forward and replaced it. Still need to work on the interior a bit and rear suspension.

damn, that car looks great. would that turbo kit/intercooler fit with the stock bumper? those are great numbers for having 6k in it. does it have the heads from a crown vic (PI?)?

i imagine it would fit with the stock bumper, this car came with the termi bumper. Put a 03 vic motor in it, so its identical to the mustang other than the covers and intake. i was pleased with the power it made... its literally all stock car minus the turbo and supporting mods. plan on getting a shortblock/turbo cams together next year and shooting for 600 on pump.

so is it possible to have all four O2 sensors and be the PCM. I have taken it to several mechanic shops and all they come up with is the PCM. My next step is to go to the dealer and program the new PCM i purchased since i get the theft engine code and car will not start with the new PCM.
