try unplugging the mass air flow sensor and driving it,it will throw a code for that when unplugged but it could have an "in range" failure which will not set a code while plugged in,hope this helps,also..has it been tuned up? what type of plugs were installed? was a complete tune up done? u could also try removing an O2 sensor and see if your problem gets any better..it could be a plugged catalytic converter,good luck
