05 pacifica 3.5 power loss
I can not get above 10 mph. I have changed the EGR, Trottle position sensor, MAP sensor, an O2 sensor and I verified that 58 psi was at the engine using a fuel pressure test kit. I need help. The car seems to run worse after changing all these things. Now when I press the gas you can hear the engine bogg down and then it stalls. I still have a bank 1 sensor 1 and a bank 1 sensor 2, which is the one i changed, code. 
i am out of things to try.

58 psi at idle??????
2 things....Take the gauge, route it up under the hood and tuck it under the wipers, so you can see it from inside the car....(MAKE SURE YOUR CONNECTIONS ARE TIGHT< AND NO LEAKAGE) Now...drive the car, and make sure the pressure doest dump when you accelerate......
2)...Remove BOTH 'PRE-CAT" o2 sensors , and drive the car. If there is an improvement when you allow the exhaust a place to escape you will be expecting a plugged converter......Only long enough to evaluate your issue...Any exhaust leak is a potential fire hazard.
