Hey guys,
have an ae92 trueno, just did a headgasket replacement, everything is back on and it cranks fine, but once its turned over it gives a mighty rev then just splutters and dies. If given a bit of throttle in neutral it will stay alive but it runs incredibly rough. And its pretty erratic.
Looking for some opinions on what to do.

- Checked timing, all good, had a bit of trouble with the CAS but all is well now.
- Getting spark, and getting fuel
- Timing is set fine
- Unplugged TPS, made no difference so reconnected (was never adjusted/removed when throttle body was taken off)
- Checked vacuum lines, as far as I know they are all connected and not leaking.

Suggestions? Help?
Thanks.
