My car is running like total shit lately. I recently replaced the following:

Coolant Temperature Sensor (for the computer)
BOTH Fuel Pumps
Fuel Filter
Cap, Rotor, Wires, Plugs, Coil

The car sometimes starts right up, other times you have to crank it for lucacris amounts of time.
Sometimes it will start and then run backwards before stalling
It stalls out at every single stop sign and red light
It misfires if you give it more than 1/8 throttle and runs off 2 cylinders
If you can get it to idle it idles o.k. but opening the throttle either causes it to stall or run rough, however when you get up in the RPM's it runs fine.

I have no idea what could be wrong with it now, thanks!
