It has new injectors gas line and filter cleaned the throttle body and still wont run right, it has a new fuel filter, new plugs and coils,injectors and new gas lines, - it stays running till you give it gas and bogs down and stalls. Any suggestions? Be kind. I'm a girl and don't know much about vehicles.
Feel the exhaust have someone rev it up or try to while feeling the exhaust possible clogging / failing of one or more cat converters
Here try this:
-Remove the mass air flow sensor and clean it. Must clean with only mass air flow sensor cleaner.
-After clean. Put it back in the take a try.
Good luck

clean out ur throttle body, just follow the hose from the air filter to the throttle body. Need 2 people to do this. Don't remove the hose completely from the throttle body. Just enuff to be able to spray ur intake cleaner into the throttle body. Do this especially if its worse when the motor is hot, as this would confirm the problem.

there are two pins one on each side that lock, you have to stick a small screw driver under each one to open them from the filter side. It is easier to remove the filter from the bracket

Check your fuel pressure it should be between 25-35. If you do not want to test it then just replace it. If you have to spray gas into the throttle body and it runs great when floored then you are not getting sufficent fuel to your engine and that is the fuel pump

Sounds the EGR valve and EVP sen is bad even if you tested it. The EGR valve cntrols idle and if carbon up will make the car stall or idle high and low (rpms going up and down) This was common on all cars during that time. I would say replace the EGR valve and senosr. This should take care of the problem. One more thing have the fuel pressure check on the car.

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.
