Yes I did jump it, a friend of mine has a diagnostic tool with a timing setting do you think that might help?

Dropped #2 cat and started car still ran rough, loud as hell and actually a quite pleasing sound, then after about 5 minutes it died.

It was sitting for about 6 months and I added 2 gallons of gas and fuel treatment when I picked it up but thats it. do you think adding more fresh fuel would help?
And if that doesnt work what else could it be?

Fresh fuel is always the first thing wo start with when coming back to a stored vehicle. Are there any diagnostic codes stored in the ECU? No, no diagnostic tool does much of anything with these cars except for a certain advanced diagnostic tool which Toyota used to make... only available through them for a few grand, naturally; You can find out just as much with a piece of wire and a multimeter.... and a book. Some tools come with adapters for this type of system but their results are usually so far off and so bizarre I really wonder where they got their info.

Purge the old fuel and put in a couple gallons of 89 octane. Run that for a bit and see if it starts to clear up.
