Answers :

Sounds to me that your cat is plugged. Try unbolting the down pipe from the driverside manifold, and pull it down a bit. Then start and rev it up again. It will be a bit louder, but if it runs fine then you know you have an exhaust plug. I had a car that I got from my brother that did that.
Check fuel pressure possibly too low fuel pump not pumping enough
