94 mustang 5.0 driving issues after off road x pipe install?
I had a new off road x pipe installed from the exhaust manifold back eliminating the cats. I now have problems which feel like misfiring. when i first start the car its fine but 1-2 minutes of driving this problem arises then the check engine light will come on and will drive fine but will occasionally reoccur. I have not read the codes just yet, but i have been told the o2 sensors are probably reading incorrect which i can fix with a MIL Eliminator, i have also been told it may be the map sensor. any ideas?
Since you do not have Catalytic Converters your check engine light will come one with an Oxygen Sensor related code. This will cause the ECU to make the car run rich and perform less than optimally. I suggest getting some MIL eliminators or tuning it with a chip.

^^ Plug in MIL eliminators may work, but you will probably have to modify them.

^^ This 4-bank Eliminator chip would not only be able to turn of the signal from the Oxygen Sensors AND tune the car to run properly and optimally with the performance parts you have on your car.
Hope this helps, Good Luck!
