1987 Ford Bronco could this be a bad computer?

i have replaced alot of things including distirbuter rotor iac all vacum hoses both fuel pumps replaced gaskets new fuel filter air filter. right at startup it idles weird for about thirty seconds then its fine but when i put it into gear and start to accelerate it hestitates some times it stalls and other times it keeps on moving and then it misses at high speeds and sometimes jerks alot at high speeds i have also gotten timing fixed and idle fixed. i have also changed all plugs wires and fuel pressure regulator and vacume regulator new alternator also
