anyone have any ideas on these codes? i tried lookin them up on google and found that the PO321 code has to do with spark and from what i read the PCM needs to be replaced is this true?

The 18X you mention is on the crank sensor. This points to a bad sensor. The PRDNL code is common to see with a bad crank sensor as the car dies and restarts on it'* own in gear and the pcm tosses the PRNDL issue.

At this point your best course of action seems to be replacing the crank sensor.

I had the same problem on my 96 SE with only 69K miles. I went to Advance and had them check the codes. Got the same codes and did some research. It'* your crank sensor. I replaced mine and it went away. Car ran like a champ. You will have to remove the harmomic blanancer which was pretty hard to do. Good luck with getting it off.

no, but make sure the sensor is lined up right with the tone ring.
I find it easier to remove the balancer with am impact gun and air hammer..
