This thing is so frigging frustrating I really dont know what the hell to do next......
As stated above, your relay is fine.
There are many things that can cause the car to run poorly.
At this point, my tests in order would be the following:
Fuel injectors (ohm with dvm) Fuel pressure (with gauge) Inspect plug wires (physically check for cracks, wires are seated, also run car in dark garage and mist water around them to check for arcing) Check for spark (spark tester) Check coolant temp sensor (ohm values vs temperature) Check for clogged cats
Also, you didn't give us much background info on the car as to what maintenance has been done or what lead up to these problems. Anything you can tell us might help us diagnose things better.
