i have a 2001 focus se with the 2..0 zetec dohc with the 5 speed, it is missing at idle and idles low, and i think it feels like it has almost no power below 4000rpms and if you are going up a hill in 5th gear it will loose speed with the pedal to the floor.

i have put a used engine in that only has 75k miles on it and installed a new clutch,

below is a list of things that i have done to try to fix the problem.

new pcv valve, new pcv hose, EGR delete, new fuel pump, new fuel filter, new fuel injectors, new fuel presser sincer<--- the thing that goes on the end of the fuel rail witch the hose goes into, new spark plugs, i have tried swapping out my coil and plug wires for the old ones that cane on the car as appose to the ones that were on the used engine that i bought, i have also checked for vacuum leaks with smoke tester, and the car shows no ecu codes.

i feel like the car has like no power below 4000rpms, i even raced my dad in his 2002 kia spectra, he has the 1.8l dohc with a 5 speed and from a 20mph roll up to 95mph he pulled about 3 to 4 car links, yet on paper his car is slower, so i dont know if my focus is just that slow or if something is wrong [boxface]

What is the mileage? Has the timing belt been replaced?

Tired of having threads polluted by this. Feeling abused. I refuse to help.

the mileage is 172k on the car and 75k on the motor, and no i haven't changed the timing belt yet but it looks good, and i do have a new one and the ford tools to do it

usually bad front o2 or TPS or vaccum hose leak maybe dirty intake maf not tight..air leak after the maf iono it can be a million things

it already has a newer engine that only has 75,000 miles on it it does not have any vacuum leaks I have already checked all of it the the o2 sensors are new the mass air flow is tight and in good condition I have already installed a new throttle position sensor the timing belt is not new but the timing marks are still alive and I have checked it with a timing kit and install the pin in the block to make sure all timing marks are correct so timing belt can be ruled out of the situation
