Just changed out my plugs and wires. Car starts roughly. Then stalls out. Checked firing order 10 times. It's correct. Wires all snapped on. Gap good on plugs.
Still nothing.
Any ideas would be great. Thanks.

Did you get it running?
If not did you check for codes?
Have you tried a quick shot of start fluid? That can narrow it down.
