Drove my car yesterday for the first time after opti replacement. Drove car bout 5 mile and it died. I restarted and then stopped to get gas. Went to start again and it would run then quit. I did get it to run awhile but everything was cycling like it was loosing power and regaining power. Checked batt and alt connections. I believe it is PCM or possibly a ground prob havent checked that. The cycling is not random but even period between each cycle. Thanks.

Put car on scanner today with datamaster, just logged with key in run position but not running and it said bad checksum, checked the edit file I loaded and the checksum was good. Anyone seen anything like this or know why????

 

Anyone
