I did 19lb injectors, manifold (new),fuel filter, 4.0 T/B, electric fan and new timing chain on my 95 2.5 Jeep. Started her up and was pulling codes 13 (No change in Manifold Absolute Pressure sensor (MAP) from start to run) and code 27 ( Logic module fuel
circuit internal problem or TBI injector does not respond properly to control signal)
The manifold is connected to the down pipe with o2 sensor in it but is cut off 5" after.
The Jeep seems weak and to wanna stall in all gears but doesn't and idles fine.
Any thoughts on these?
Thanks in advance.
