Yes he checked for codes and not one code came up.
Also there was no check engine light on.
He checked for a bad O2 sensor and on the scanner the pre and post O2 sensor. The pre O2 sensor came up all 0's were the post O2 sensor fluctuated with numbers. So he replaced the pre O2 sensor and it started up right away, but now the Check Engine light is on! So we now have got the van running, but the check engine light is on do you think the post O2 sensor is bad also?
