Fuel Injection Question

is the check engine light on ? If you don't have any diagnostic info data of any kind ,check the o2 sensors with a lab scope/ graphing volt meter or just a dvom for response. Check map sensor frequency I did not beleive those had air flow meters are you sure this is not a variable venturi. You can check the air charge temp senso/iac valve if equipped they gumm up pretty bad, clean throttle bore and blade. Don't mess with minimum air screw unless some one else has srewed with it. Than check the TPS sensor. orry have to go now.
Good Luck,
Mike
