It was a nice day today so I decided to put the battery in my car and start it and let it run. It ran fine for about 20min then it started to run rough going from 600rpm up to 2000rpm it did that a couple times then it died. The gas has stable in it and the battery was out of it and it ran perfect before I put it away so if you have any ideas thanks Jason

 

As you can see I'm posting the same problem ie;"Stalling problems" posted 2-5-05. I'm told it's the Opti I wonder how difficult it is to change.?

 

The opti isn't difficult to change - just time consuming. You can try a search - there's a lot of posts on changing the opti (probalby more on that than just about anything else). Basically you need to remove the water pump, AIR Pump, then pull harmonic dampener and remove opti. To pull the dampener you do need a balancer puller tool - you can borrow one @ autozone etc. if you don't have one.
