01 focus,2.0 DOHC ZT,Crapping out under acceleration or under load on hills,Changed fuel pump,Checked for vaccuum leaks,No codes no light,I have a streaming reader and everthing appears to read right.I am...
Under a load or uphill,would suggest that a high vacuum signal was involved. So think EGR Valve. I know you got no codes. This is an exercise in logic.
A misfire will present it'self going up hill or loading the engine. e.g. hard on the gas
What has no sensor or won't set a code easily. Vacuum leaks,air filter,all air intake ducting,MAF Sensor,Throttle Position Sensor and don't forget those really small EVAP Leaks,most people never heard of.
Is the converter partially blocked?
O2 Sensors switching properly?
Fuel pressure,under a load? New fuel filter?
