Friday started the tune on my car after we had to put a new computer in, Everything was working fine, wrote several times to the PCM with no issue. Car would rev fine.... Now Monday I am having problems writing to it, sometimes it works and sometimes it doesnt....and will not rev at all, pushing the pedal to the floor while idling the inj duty cycle goes to 0%........

Has anyone had this happen, or have any idea?
