But after that she was running fine.

I took her to my garage and changed the fuel filter, in case it would be clogged. But didnt notice anymore problems 'til last week; i was about 1 mile from home when she started stalling and misbehaving. It took me a couple of restarts and some foul language getting home.

Today i started her up, and she's acting all weird again (i got a video that ill upload once i get home).

So; what do you think? No CEL and it only occurs sometimes. I figure it has something to do with the gas delivery since she would only respond and ignite on motor starter on christmas.

I can upload a torque report and a video later tonight.
