afc tuning problems- car misfires sometimes

[95gstsilver]

i have a 2g awd witha 1g head swap, 91 cas and rewired all that i had to. i put in the afc as well. for some reason my car runs really lean (close to 18 air/fuel on wide band) after adding fuel with the afc, it gets better, but i also have a problem with the car misfireing. or at least that is what i think its doing. when it misfires, if i turn the car off, then back on it clears up. any help would be appreciated. thanks

What injectors? Did you boost leak test? What's your base fuel pressure? What type of wideband is it? Can you post a datalog?

dejon 770's, boost leak test good, 40psi fuel pressure, aem wideband, i have no datalogger. we got my friends car scanned today and it said that their was random misfire. i was just wondering if this could be from the cas. if the cas was bad, could it cause this? what about the tps, on the afc, when my foot is off of the gas, then it still reads that there is a throttle signal. i just dont get it. my friend and i are gonna take the cas off of my 1g and test it on his 2g to see if it works out. if it doesnt, then i dont knowwhat the hell is wrong.
