so ive changed out the ecu with another cfi ecu, ive got new plugs, leads, cap, coil, air filter, oil filter, oil, fuel filter and fuel pump. now the car starts and drives but once it get warm it just doesnt wanna go lacks power, when overtakeing it feels as though it just tried to bog down and you can feel it hesitate at full throttle but if you release the throttle just slightly it takes off. ive done a trans service and adjusted the bands, reset the ecu, had the injectors cleaned, and still it just doesnt go, i know cfi injection makes the car one big slug but it should still at least light up in the wet and it doesnt. if i change gears manualy it get hot very quickly.
does anybody have any clues to what the nature of the problam could be and how to fix without converting to mpfi.

check the ignition timing.....

checked the timeing it's pretty much spot on,

did you check it with the ecu in diagnostic mode? or just put a timing light on it??

yes i did do it while it was in diagnostic mode, had my old man help me with it because he's amechanic but hates the system that my falcon is running, he's got no idea what the problem is either he told me to write up on here to see if anybody has had the same or similar issue.
