Hi my Ford Au is giving me some problems after I charged its battery without taking the battery terminals off.It starts and idles ok but when you press the accelerator it flats spots and doesnt want to run at all.I tried a new Tatarini Gas Computer and a new stepper motor ,but still the same thing.I put in a manual stepper motor and it runs with that.I want to put the electroni stepper motor back in.Anyone have any ideas what I should look for now.
Thanks

have u tried disconnecting the battery for a bit and then putting it back on and resting all the computers that way. i don't know if it will solve it but its worth a shot.

yeah as above reset ecu
